Well, I just took the plunge and ordered TacOps 4 ($25 is relatively cheap, but the time spent playing will cost me w/the wife). I've been a long time CM player and always meant to check out TacOps. I finally downloaded the demo Monday evening, buzzed through the tutorial and was hooked. I can't wait for the full version to arrive.
Once I'm done dealing w/the AI, I'm sure I'll be getting whooped on by y'all (and hopefully dealing out a bit myself).
Cheers!
