Grand Theft Auto IV: The Lost and Damned
Apparently, Gang Wars can only be initiated from a bike. So, not bothering with any more of those. Motorcycles are generally better in Lost in Damned than they were in GTA4; specifically, it's more difficult to be thrown off of one. But, due to the laws of physics, they still can't do high speed turns very well. Cars are still more fun.
For that reason, and because the storyline is relatively weak - not to mention, a little spotty (it has a Kane & Lynch-ian quality of some plot points being completely unexplained) - The Lost and Damned fails to meet the high bar set by the original GTA4. But it's certainly still a good deal of fun, and worth playing if you enjoyed Niko's adventure -- not just for the intersecting story points, but also for the new weapons. Two words: street sweeper.
Better than: Overlord: Raising Hell
Not as good as: Grand Theft Auto IV
If you thought bike gangs were scum: TLAD definitely won't change your mind
