Well, we used Renderware on our first game on PSP, and it wasn't exactly perfectly tuned for PSP. After we removed it for [Death Jr. 2], we found our framerates hit 90fps... before we knew it, thanks to our fantastic tech staff, we had light blooms, High Dynamic Range lighting, and lots of other lighting and frame buffer effects running in the game. The net result is that we've probably got some of the most technically advanced features of any title on PSP at this point, which is pretty cool. We've done a lot more than that as well; I think people will be pleased by the tech in the game, and our loading times are still extremely short.Can this really be possible on a handheld? Death Jr. 2 seems to address the problems of the original and throws in a multiplayer co-op mode to boot. The sequel comes out this Halloween, but until then, don't forget you can check out the original for only $10.
