"Tactical" is the key word here, though.Complaints about complexity make even more pissed off: complexity doesn't always make a better game. Not to mention Civ5 has much more tactical depth, and culture, gold, and policies are more complex. hey simplified some areas, and made other areas more complex. Plus, other civs war agaist each other better, and you aren't forced to expand to compete in the harder difficulties.
But I agree with you that Civ5 gets criticized too much, despite my constant scepticism here. If we would all remember how bad Civ4 was on release, there's still much potential, and everything that won't be patched can definitely be modded. But I predict that RFC for Civ5 will differ more from its vanilla version than its Civ4 counterpart.
Because obviously, the 2.0 GHz Dual Core is the weak component.
Buying tiles by cities is really good. Not seeing if you connected a resource and what it gives is crappy. Map is really nice but hardly-readable. There are too few technologies but they are OK (that's why GS are broken). To sum the things up I have to say that ciV is much better than I thought it will be
