I could probably say something in the DOTA 2 thread and talk about the beta there. Super Monday Night Combat is also fun. The upcoming KF update too, but I'm under strict NDA for that until a particular time.
But anyway, I do plan to do more of these comparisons if/when Valve adds more maps to the beta. This, while time consuming, was a lot of fun if for only getting to see just how much the games changed in terms of map layout.
Based on that tentative list of maps posted earlier in the thread, there are some great revivals that even missed a Source release, so it will be very interesting to see what happens. Plus it's REALLY crazy actually having Counter-Strike news on the site again.
