Let's start with
Torchlight, the action-rpg-loot-madness king!
I'm currently developing three characters in very hard mode, the Alchemist is the newcomer.
... and continue with:
[DS]
Nostalgia (few hours in, fairly anonymous final fantasy rip off)
Shin Megami Tensei: Devil Survivor (just booted up, it seems pretty)
Suikoden Tierkreis (half dozen hours in it, good game if you don't mind frequently random battles)
[PSP]
Class of Heroes (few hours in, it seems a nice dungeon crawler)
Crimson Gem Saga (several hours in, half dull, half nice)
[PS2]
Mana Khemia 2 - Fall of Alchemy (still sealed, PS2 is actually buried in home renovations chaos)
[PS3]
Tekken 6 (fallen in love with Law again; sometimes inexplicable slowdowns show up offline)
DJ Hero (I wished for more challenge and more electronic music, but it's good for parties; nice case!)
Batman Arkham Asylum (I'm about 30% of the game, total approvement)
Demon's Souls (I'm still dead.
what a challenging freshness!)
Pes 2010 (not bad, maybe the best lifted PS2 Pes game... Seabass, please, if it's possible... next year... don't scale up from PS2 version again!)
Katamari Forever (a fine sequel, considering Takahashi is missing)
Uncharted 2 (just booted up!)
