I, for one, was not impressed with the menus just revealed in the G4 demo. For the Xbox they might be fine, but, as a PC user, I am hoping they will make a more functional and less flashy menu system. Even for the Xbox, I found the constellation Perk tree to be overly flashy, where you could only see about 3 perks at a time when zoomed in. The Ipod-like list system would also be tedious and unoptimized on the PC.
In summary, the UI certainly looked good, but how well will it function? Your thoughts ?
