In a simpler time, Capcom made exclusive games for Sony's PlayStation. (Yes, yes, it also created Nintendo titles.) Then the Osaka-based developer started making games for the Xbox 360. After that, it started making games for BOTH the Xbox 360 AND the PS3 — games like Devil May Cry 4. Blasphemy! Mega-Man creator and Capcom R&D honcho Keiji Inafune explains:

Until now it's been hard for us to develop multi-platform games, but recently we have developed this development engine that allows us to develop a game in the engine and then put it on to PS3 and 360.

Developing Dead Rising and Lost Planet helped flush out everything in the development tool system — which is now pretty much complete, aside from the usual upgrades — so we decided to use that engine, make it for the 360 and the PS3 with Devil May Cry 4.

So, now we can get the game out into the hands of more gamers — because 360 has such a huge installed base already, especially in the US, and as game makers we want as many people to have the chance to play our games as possible.

Bringing its games to the people, that's what Capcom's doing! And we just thought it had something to do with making the most money possible on a single title. Silly us.
