I'm not sure which type of AA they used, but edge quality sure has a lot to do with resolution and T.V. quality. I played it on two different T.Vs, one is an extremely old 32in HD T.V. and the other is my 46in HD T.V. that's about half a year old. The quality on the old T.V. is NOTHING like the new one, the edges are jagged and the color is off, obviously. If you've got a newer T.V. I doubt you'll have any aliasing problems.
