Here's the deal:
Even with all the issues, I hope it can get its act together. That being said:
First off, the price: $15. Good to get in and get out. I heard that this game will eventually add dlc over time (new 'modules'). This price does NOT excuse them from the crap that's been happening, though.
This game is best for screwing around bashing monsters co-op with your friends, because the story is presented in a so-so manner (you talk to npc's and they just grunt when you click, and text lines pop up).
This is not a click on the ground RPG, it's a use the keys to move RPG. Yeah, they forgot to include the ability to configure many of your keys in the PC version. Like the arrow keys (I'm left handed). Kind of sad, so you have to go into the .ini to fix the keys you want changed (and some don't change anyway from here), or use a 3rd party utility I've been using like autokey. This pissed me off the most. I'm still waiting for the 2nd patch for this. It's the type of thing that would turn a casual PC gamer off for sure. Don't worry though, you can use a gamepad (WTF?).
Missing textures: 5 minutes in after I installed it, when you picked up certain armor or items and equipped them, you ended up looking like a pasty blue smurf. Supposedly they fixed it in the PC patch.
Ability points loss: upon leveling up, you get a few points to put into abilities. I didn't run into the issue, but people have been ripped when they built their character. Later on the player would save their game a certain way and it would remove those points. This is not cool when you are near the end of the game... Hadn't happened to me, and the first patch apparently fixes it, yet I have heard some people still complaining.
Multiplayer is tied to Gamespy.
Co-op local multiplayer does not include LAN play.
Because of all the above horseshit, they ended up getting terrible reviews.
Here's to hoping they'll get another patch in that resolves the remaining crap.
In any event, no sweat off my ass - all in I got the game for $1.50 (coupons).
