I'm loving this game. I haven't had any issues with the save system so that helps, if my save gets screwed I'd be frustrated enough to give up on it so I get that, but I'm 30 hours in and it's a blast.
I've been taking my time so I'm still in the city finishing up my last open side quest but smashing zombie skulls and dismembering zombie limbs is just a mindless good time. Been playing single player and the city has been a pretty cool escalation in challenge with enough safe spots to keep it fun. I just run from truck to truck to get to my destination. From on top I round up any zombies in sight with my pistol and then drop a deo-bomb on them, count to three, back up and watch the limbs fly. Then take out any stragglers with the old flying blade to the neck, kick to the chest, blunt to the skull combo. It's been fairly intense since I'm playing solo so it's easy to get mobbed and I spend all my cash on deodorant and duct tape (found some grenades for sale but at $600 a pop, no can do) so all my weapons are whatever crap I find laying around. I've been all over this city and haven't got bored yet.
This game is just so fun that it's hard to fret about the little stuff. I haven't seen limbs fly like this since Postal 2. I wish more games were this fun more often than I wish more games had CGI quality graphics. And I haven't even gone multi-player yet. Glad I found something to last me until Dark Souls.
I want to hear what people are doing up in here for fun. I want to hear more about what's to love than what's to hate. 'til I lose my save, then I'll be cursing the game too, I mean whoTF makes a game this big and doesn't let you have multiple save files? Anyway, lot is to love about all these dead peoples running around begging for an ax in the chest.
