i agree with Culdcept being a hidden gem. Aetiler Iris is good, but has a little to much backtracking from what I remember. I played Asterix & Obelix Kick Buttix until I got to one part where you have to kill like 700 soldiers(i kid you not) and i just can't get past that part. i'll have to give it another try down the road. all in all it was a decent game.

I am currently playing deus ex: the conspiracy for ps2 and its a really good game with questionable a.i., but fun nonetheless. I just don't know if you would consider this game "under the radar."

i might think of some more hidden gems i played later...
