I dunno, a bit more gushing may eventually sway me. If all the cool kids are doing it, sometimes I cant resist. And that's why I have a huge backlog to begin with….
I really can't gush over the game even though I couldn't stop playing the freaking thing. There are quite a few things wrong with it like Majnun said. For one, when you pick up alcohol it will sometimes switch out the weapon you are holding. Annoying little things like that that I can overlook because I've been dying to play a sandbox style zombpocalypse.
One thing I can say without a hint of regret is that the melee combat is freaking awesome. You can slice, bludgeon, explode, burn, electrify or stomp your way around the game. The weapons are nice and different even within the same catagories. Like my girl loves her some sharp weapons, but not all sharp weapons do exactly the same thing. For example an axe (or even a scythe) is more likely to chop off an arm than a knife or even a machete. There is one weapon I do not enjoy and that are guns. They are boring and hit exactly where you aim every time if you aim using ironsights. I can headshot my way past a horde or human opponents. Not human like in co-op, but human like not zombie
If anyone wants a shooter then play L4Dead, but this is all about melee and throwing.
There are a ton of things wrong, but it doesn't matter to me. I just love going around surviving this hell on Earth with my chick who is so bad ass she walks around the sewers and in the jungle in high heels.
Around hour 20 I was starting to get a little bored with the game, but then I encountered the middle of town. That place was awesome. It threw everything at me and the kitchen sink. When I survived that place my adrenaline was pumping and I felt like I actually accomplished something. I go back there anytime I start getting a little bored again. Even the jungle is no comparison to the middle of town.
The main plot sucks big time, but I enjoy some of the sidequests. A lot of them are your usual "bring me blah blah blah", but a few of them are unique like when I had to drive around town to turn off some of the fire hydrants or putting up posters for this guy at the church.
Since you got a backlog I'd say wait until the price drops. I'm having a blast in this game, but I know it's not for everyone.
Edit: When you do get the game make sure you search everywhere in the jungle. There is an easter egg there that was great. A nice hat tip to a classic horror series.
