For some reason there is a gross conceptual error about the way a stat system works. If you don't have a game mode that RANDOMLY matches players, stats are pointless. I could buy two games and play against myself all day to get my 100% win percentage. Don't even bother keeping stats unless you look at adding in a server hosted match up system. I really think it is what this game needs. I have the game shelved until I see some promising news on this.
I disagree. Stats would not be pointless because most people you play are going to be random anyway.
Also, if you're shelving a great game like Sins then you're stats are really going to suck when you come back because you're going to get owned since most of us are getting better and better everyday.
Go ahead and shelf your game. Leave as a newb, come back as a newb.
Cheers!
