Yes, more options --> more fun --> better game.
More units and I'd just love 4 different UU's for each civ (1UU/era).
More stack commands (maybe introducing control panel for group commands such as in AOE2),
easier queuing (not very intuitive right now),
news screen such as in MOO2 (easier for following up production)
I'd buy the XP immediately!
(that is if you don't wait for too long anymore)
PS: where are the promised correct starting locations on world maps? Mike was working on it several months ago ... Don't tell me that I'll have to dive in the editor, please
