Vegas simply rocks my face off!
The first thing i liked about the game was the customization for characters and weaponry. Even though the guns are a little limited, hopefully they will make that a little better next time. The guns are pretty well balanced, on single player that is. I have yet to play MP. Once in the game I found the cover system to work quiet well, not perfect but good for the first time they used it this way. The graphics were the best I had ever seen at the time, they are still good today but there are some games that have better. I still can't get over the blood splatter effects, absolutely awesome imo. Some of the destruction effects are bland though.
The gameplay was good too. The AI could be better on the easier difficulty, especially your teammates. Realistic difficulty made it worth playing through a second time for sure. The controls were good. Sometimes my gun wouldn't shoot, it shot more than it didn't though. The sound was great some of the best I have heard. I haven't shot any pickups with a twelve gauge but I imagine thats about what it'd sound like.
All in all I loved the game still play it when ever I can.
