The ideal scenario would be something that batshit gory with lots of ripping and tearing, very over the top. Something that plays sort of like Brutal Doom, but is more modern. I finished Dead Space 1 and am working on 2 right now, and I got an unreasonable amount of satisfaction from Isaac's D̛̛E̴A̸T͏̨̕H͏͟͝ ̷S̸͠͠T̕͢O̸M̕P, so much so that I thought "Hell, if there were a game that was just this, I'd be satisfied."
So now I'm looking for one for the good ol' catharsis factor. Any suggestions?
