So I'm getting Black Ops.
For PC on Tuesday? Is it worth it? Hows the gameplay on PC? Laggy? Lots of maps? Lots of weapons? Good sniper rifles? +Rep for helpful answers. 
Maps apparently suck a little, but I found them to be ok.
Snipers are still broken, QS with them is hell different from MW2, but still possible.
AUG/FAMAS are the only guns worth using, and killstreaks are still as OP as ever.
Depending on your PC the game may or may not run. So long as you have close to the min specs, you in theory should run it, but the game is so un-optimized for PC it might not.
L96A1 is the only decent sniper, that and the WA2K. Others are just not powerful enough to justify using them with their gimps.
But it is fun, and if treyarch would iron out some of the issues with it, it will be a great game. Certainly more quality than MW2 was.
