I got DayZ too, mostly because I suspect a price increase later on. But I will wait until it's more or less "finished".
Skyrim is moderately entertaining, but the artwork is great. Mods are important, and 3GB VRAM should be perfect (2GB is not enough).
I got Total War, but was disappointed, due to performance and AI. There's a visible "line" between close and distant graphics, beyond which units clearly change color and model, which is annoying. For a studio as big as that they should've been able to make a continuous/blurred transition instead of a sharp discrete.
