HyperDevbox specializes in PSP to Android conversions. They ported Spectral Souls earlier this year and just finished work on Generation of Chaos. It’s a strategy RPG from Idea Factory, but not your typical move your heroes on a grid kind of game. Read this mini strategy guide NIS America created for the PSP version if you’re thinking about giving Generation of Chaos a try.
The Android version has touch screen controls and an option optimized for tablets. HyperDevbox also says they reduced load times and the 30 on 30 battles are smoother than the PSP release. Performance will probably vary between Android devices though! Generation of Chaos is fully localized in English and available for $15.
