I can find simplified games or shoot-em-up's without much effort - there are lots of them out there.
GalCiv is a TBS, its designed to be a thinking game, with battles along the way. It should stay that way - simplified shoot-em-up's are not hard to find, and I for one can live without them.
If anything GalCiv has much scope for more "stuff" (define "stuff" according to personal preference) as PCs become more powerful, and the latest jump to 64 bit. In that regard its following in its illustrious predecessor's footsteps - Fireaxis Civilization Series.
The Core factor however, is GalCiv was designed from the start as a thinking game, a strategy game. In many ways the first two set the scene, rather like the infamous Civilisation Series I & II - with the latter, the big breakthrough was Civ III because the ground work had been laid, and developers were given their head. What followed was the famous Civ IV, arguably one of the best strategy games there has ever been.
As long as Brad stays true to his instincts, and I believe he will, GalCiv 4 and on will follow in Fireaxis footsteps, and I believe - in the long run - will be as big if not bigger than Fireaxis Civilization series.
Against that backdrop the euphemistic Pacman with a six-gun doesn't appeal
