I purchased BattleBit the other day for $15 USD and I am enjoying it so far. The community seems pleasant at the moment. The developer-run servers have strict rules against being an asshole and a zero tolerance for spam/racism/politics, so that's definitely a plus. I can play the game instead of muting people constantly.
If you're a fan of Battlefield (1 or 2) or Project Reality then BattleBit might be worth checking out. The pace is as fast or slow as you want it to be. If you prefer static defense -- go for it. If you want to run into the fray to drag incapacitated players from the field while tracers whiz by -- go right ahead. If you want to employ teamwork and tactics to capture objects -- no one will scoff at you.
