What about BF3? Does anyone that plays it know the ratio of empty servers to full ones? Might be worth a shot since some of those servers can host up to 64 players.
Not sure how many people here play it though or how popular it is overall.
Really hard to populate new servers, and is a lot more demanding on resources than cod4 I believe.
. I can however get a discounted rate and we'd look at something around $65 for 48 slots. Even so, it's not something I'd like to fork over knowing it'll be roughly an empty server anyway. We're already too late in the game for this game. Maybe when BF4 comes out, but we'd need a majority of our members committing on buying the game as well as populating it.
