never played resistance2, just 1, played killzone2 though and it's pretty awesome. I should checkout the gameplay for resistance 2 then decide if i actually want it, but it's true that 1 did leave a bad taste in my mouth.
I keep wanting to go back to City of Heroes/Villains, but I never do... architect edition may be nice... then again later this year Champions Online will be around... I think i'll wait for that.
