I've been meaning to try the demo of the XBLA version of Galactrix - I bought the DS version the day it came out and ended up getting rid of it the next day. Constant loading, horrible stylus recognition; those are big problems indeed, but the deal-breaker for me was the shifting battlefield. They couldn't fit the board and both side's skills on one screen, so it shifts every turn. No big deal, except that it was actually making me motion sick to the point that I couldn't play it.
Honestly, these faults are inexcusable when you consider that COTW is an older game, and had none of these problems.
I'm wondering about how PQ handles with a controller verses a touch screen, but I guess I'll find out when I nab the demo. :)
As CAD once said, everything's better with lasers. Well, except Alderaan
