Going by Game Center leaderboards and assuming about $3 revenue per game:chempop wrote:What I'd like to know is what kind of profit they've made from iOS ports?!
Bug Princess: 10,547 = $31,641
Deathsmiles: 23,161 = $69,483
DoDonPachi Resurrection: 42,134 = $126,402
Espgaluda2: 26,216 = $78,648
These numbers are taken from the maximum participants in a leaderboard for a game. The actual sales numbers should be higher due to people who never signed up for Game Center and people who haven't posted to a game's most popular leaderboard. I'm also using slightly low revenue estimates. (Example: Bug Princess is $5. I think devs keep 70%, meaning Cave gets $3.50 per sale.)
I'm not sure what Cave spends to develop these games, but my understanding was that they wrote a library that converts their arcade hardware's graphics calls to equivalent iOS graphics calls, allowing them to use most of the arcade code. They probably invested a good deal of effort writing that library to make the first game, but porting additional games is comparatively easy.
I think the Bug Princess port was completed in less than 6 weeks of programmer time. Possibly part of a mad scramble to increase shoot-em-up revenue before year's end and hopefully save some projects that were on the chopping block.
