Does anyone know if there's a way to check whether or not an online game for the Xbox 360 is still being played regularly or not?

I ask this as I'm considering re-buying Soul Cal 4 and I want to know if anyone still plays it before I do.

I think the easy way is to see how many people are playing the game when you attempt to play a quick game. If there are none, you know the online play for it is dead. Either that, or you just aren't on at the right time. That's more of my opinion than fact, by the way.

As for SCIV, I've been on there, and there's plenty of people still playing (including myself). I'm no good at online SCIV though, cause everyone's more experienced than me.
