Wow...lot of stuff popping off in March.
Nevermind DOW2: Chaos; I ain't even got DOW2 Vanilla yet!!! Hell, I still need to play Dawn of War original - which I do have and bought dirt-cheap, long ago. Yeah, I do have DOW: Gold Edition (Retail) + Dark Crusade (Impulse).
About DAO - Awakening PC...too soon to call on that one. I don't really know enough on the expansion and its length to justify the $35-40 price-tag here. Maybe $30? I dunno, but I still am in the midst of a bunch of games already, as is. Namely, in the midst of one big RPG already - Divinity 2: Ego Draconis. Plus, I want to get Mass Effect 2 PC.
About Metro 2033 - looks cool, but not completely sold on it for full price ($40 or more). Definitely something to look at, when it drops to $30 or below.
Bad Company 2 - not yet. I still ain't played MW2 PC yet even.
I think AC2 PC comes out next week...but right now, screw UbiSoft and their crappy-ass DRM scheme. Until they come out w/ a reasonable DRM scheme, I ain't buying it until it's like $10 or less - the price of a rental or something.
