Desktop Tower of Money: 3 tips to profit from casual games

74 Comments

DTDSo here’s a couple ways to create a successful game online: a), Find an investor who’s crazy enough to give you millions of dollars, or b), Put it on a distribution network and hope you get enough customers willing to buy it as a download.

Then there’s c), Make a Flash mini-game, let people play it for free, and watch the ad revenue pour in when the site gets 20 million pageviews a month. That’s the option Paul Preece took with his phenomenally popular Desktop Tower Defense, and though he has no professional experience with game development, the Visual Basic programmer is now making, by his estimate, high four figures monthly for his ferociously viral little game.

As such, it’s an ideal case study for an often-overlooked revenue model for online games, one that developers and investors would do well to learn from. Working with a low budget on a game designed for maximum stickiness, a small team of developers can create a single title which earns thousands yearly— or in Preece’s case, close to six figures.

After the break, Preece explains some of the secrets to Tower’s success.

Take a Well-Known Genre, Make It Better

There are numerous “Tower Defense”-style games with the same premise—stop a horde of monsters by building a variety of defense towers. “I have been mulling over doing a proper ‘mazing’ Tower Defense for a year or so,” Preece says, “but I felt that the learning curve for Flash was too great. Then a good friend of mine created the successful Flash Element Tower Defense, and when I chatted to him about his experience… it suddenly seemed much less difficult than I had thought it was.” [His specific inspiration was a mini-game from one of Blizzard’s classic real-time strategy titles: “The basic map layout was based on Autumn Tower Defense, which was one of my favorite Warcraft III TDs.”] Though most of these games are fantasy-oriented, Preece gave his version a quirkier, more cartoonish feel, and added a number of elements that made it more viral— particularly a group-based ranking system which encourages competition between friends and co-workers.

Promote through Web Aggregation Sites

“I didn’t do any promotion of the game beyond sticking it on StumbleUpon.com,” Preece tells me. “It gave the game a slow start for a week or so— which was good to weed out the bugs. Then it got ‘picked up’ by a few large game sites, then Digg and then I-am-bored.com. When DTD got Dugg the first time, the server overloaded and I realized that it was becoming popular game.”

How popular? “I am unsure as to the number of unique visitors,” he says. “My logs show 4 million visitors and 20 million page views for April. The game itself has had 9 million plays during April (excluding older versions).”

Debuting in March, his site, http://www.handdrawngames.com, is already among Alexa’s top ten thousand sites.

Profit Through Ad Revenue and Keep the Budget Low

DTD’s main revenue source is AdSense, but with its avalanche of popularity, advertisers have approached Preece directly, leading to “Affiliate deals, sponsorship, custom versions for other companies etc. The last two are in the pipeline but I thought I’d add them in at a low level.”

Preece’s main expense is running the server. “Hosting fees are negligible,” he says, “at $130 per month. But I am getting very close to the 1200GB bandwidth allocation!” That plus “the continuous supply of late night Red Bull” comprise the bulk of Desktop’s budget.

“I do feel that with a little more market place knowledge I could make a good living from DTD until it stops being popular,” Preece e-mails me. “With less popular games I would probably need two-three on the go every month to make a good living. That would equate to releasing a game every month which I think is doable.”

But what’s that odd voice you hear, when you win the game? “It comes from a children’s cartoon I grew up with in the UK called ‘Ivor The Engine’,” Preece explains. “It was about a Welsh train, which is where the accent comes from.” But keeping the budget low is his main consideration. So, he adds, “I have removed it in the next version for bandwidth reasons.”


Update, 5/28
: Added Preece’s acknowledgement of Warcraft III as an inspiration for DTD.

This is the best game ever, and it was made with no funding, and is pulling in lots of money for its creator. Their new site, casual collective is continuing on that tradition of low cost high return.

It’s really refreshing to know that you don’t need millions of dollar to make a successful game. All you need is some inspiration, and a quality game idea that can be readily accessible by the public.

Totally addictive game. I’m hoping to follow in Wayne’s footsteps with my own game site that will hopefully help me to fund a startup…

John Tan

It is a good game. Independent game developers (like myself) can learn from this. Question to Paul if you read this: Can I include the game on my website?

This article has inspired me to follow-through with Paul’s revenue model for an original web-based trading card game that we have on alpha now.

djmoya

This game is brilliant and addictive cant wait to see what projects this guy has in the future

waffles

how do u make a tower defence game i got a great idea for one but i dont know how to make it

scaR

LOL @ you guys. Well I guess you all are new to TDs.

Play the original Autumn Crossing on Warcraft III, you would all be amazed. Instead of one square it’s four players, so some co-op work is required to win.

Plus when your friend costs you the game you get to say OMG YOU NOOB!

Brains

Ahhh yes, my boss and I wasted many days of work playing this game. Well done :)

Jaz

Dood serisouly good job on this, i can honestly say that i spend more time playing this than i do world of warcraft hahaha jk’s but i look forward to the second installment…

I can see why the game has become such a big hit, give ’em credit where credit is due. They deserve the success they’re getting with their game.

silon

Forget Warcraft, this is the best thing since Dune II

Jamax

That money should just barely pay off his lawyer when psygnosis sues him for ripping the lemmings sounds effects… great game, but Lemmings was 10x better.

Wagner James Au

Paul did tell me it was based on Autumn TD from Warcraft III, actually– it’s my fault for editing that mention out, will add in an update.

This flash game is a weak rip of one of the best Warcraft III tower defence maps that was ever created. Autumn Crossing tower defence. It’s not really well tuned, it’s dumbed down a notch.

GJ on bringing a great TD to the browser, but give credit where it’s due.

Bryan

Please, don’t mention Warcraft 3 or Starcraft anywhere. The game came directly from it, and no one seems to remember that.

This is such a well-tuned, addictive game. When I was at Railsconf everyone was talking about the hours they’ve spent playing it.

Underduck

I absolutely love this game and spent many hours playing this and I think you should get a developer for Xbox Live Arcade to really get this game started. It deserves so much more for all those hours.

Bart Noppen

The concept of tower wars comes from a very popular Warcraft 2 custom game which is played by thousands on Blizzards BattleNet. There are like a hundred different versions and it looks cooler on BattleNet then in Flash :)

Alex

This is my plan exactly for the next couple of months – learn flash, program some really cool games and quit my job to move to hawaii with the millions earned from the games.
I hate you guys for telling others this secret. Shame on you! :)

Wayne

Nice job Paul. I have spend countless hours on this game — it’s the right amount of complexity and fun to provide for a truly addictive game. I also started a game site on a shoe string budget and in my spare time. It is now doing over 10m page views per month and ended up funded me while I started another company. God bless the internet and people with too much time at work.

Jim Greer

This is such a well-tuned, addictive game. When I was at Railsconf everyone was talking about the hours they’ve spent playing it.

It’s the highest-rated game on our games site, Kongregate (out of nearly 750 uploaded to date). Also the best-performing Google search term we see.
