See as how I am losing interest in my PSP/DS and seeing as how many people here are fluent in portable gaming I would like to ask the aforementioned(thread title) question to anyone with input.
DS: Final Fantasy Tactics A2, Pokemon Platinum, Professor Layton and the Curious Village, Phoenix Wright series, The World Ends with You, Rune Factory 2 PSP: Lumines, Tales of Eternia, Syphon Filter, Disgaea
this isn't a repeat thread, but this thread is interesting and has people's favorite ds game: http://forums.toucharcade.com/showthread.php?p=164068#post164068
I'm in the middle of Dementrium on the DS, and I have to say, it's about as scary as you can get on a portable.
