I tried this topic over at GAF and ended up with responses like FF:CC and FFTA2. (White Man's and other intelligent responses were appreciated.) So I'll pose the question here: What's the best portable substitute for Diablo's lootin'?
I remember folks around here enjoying Alien Syndrome, iirc. I did try Rengoku 2, and that was pretty strong, but the level design didn't keep my interest for very long.
Candidates from the other thread: Bounty Hounds, MHF2, GBA LOTR RotK, uhh, PSX-PSP Diablo.
