Don't laugh at me but Xenosaga, 1 and 2 anyway. I beat 3 without TOO much trouble, it's almost a shame the series ended there because they had finally hit their stride in the gameplay department. 1 and 2 are so god damn slow paced battlewise, and coupled with the extremely cheap/difficult bosses.... well, it's a bitch to play through! I mentioned this in a THINGS THAT PISSED YOU OFF IN GAMES topics awhile back but I'll never forget the time I spent like 30 minutes fighting one boss in XS2, carefully setting up my strategies, wittling him down, preparing for the final blow when I accidentally entered the wrong ATTACK COMBO and he promptly fucked me up. It's completely unforgiving a lot of the time.
I don't really like challenge in games. I mean, I like to have to use a LITTLE strategy and stuff, sure, but I hate being cockblocked just because I'm not TWINKIN MY DUDES and grinding ridiculous levels and shit. For me, fast paced/smooth gameplay and an interesting story are the best things I can look for in an RPG.
WHY SO SERIOUS HAHAHAHHAHAAHAHAHAHAHAHHAHAHAHHAHAHAHAHAHAHAHAHHAA
