Great dark humor RPG
The thing that those lacked that Fallout had is that you don't have to follow a direct path in Fallout but in almost all other games you do. The constant time limit in the game is the biggest draw back. It would be more fun if you could wander around after getting the water chip than having to be stuck with just another time limit.
There is a few inovative aspects to it that I find quite enjoyable such as the percentage chance to hit your target (even more indepth if you are going for a certain body shot) which didn't make a lot of sense all the time like when using a sledgehammer.
If you like games with a sick sense of humor and don't care about graphics; just gameplay and story lines than this is the game for you.
