I'm debating between the original L4D and L4D2. I like the original better, but I'm worried that I'm going to discover that there aren't any/many games.
Is there a way I can see how many people are playing a given Xbox Live game at a given time, or in a given time period? Specifically, I want to do this WITHOUT owning the game and I also want to know if there are people within reasonable ping distance of me.
