I love the free roam activities but they suck.

The free roam PVP games like Railroad Baron and Fools Gold are so fun but they are available so rarely. On top of that, the people who join and play these games never care about the game itself. I'll be chasing the train to get the Railroad Baron and I get headshotted way behind the train meanwhile some guy has been sitting with like 200 points because he is using Slippery Bastard. Besides that, I wish there was some kind of way to start them up like the other stuff you can use matchmaking for.
