However, I have read a LOT of the complaint threads, and much of the disappointment falls into one of three or four categories, those being:
(a) the game won't work on my computer-well, thats a legitimate complaint IF your computer meets the specs, but even I am having minor graphics difficulties with Civ4 on my computer, but most of them are related to the ATI drivers I have-which is hardly Firaxis' fault IMO.
(b) I don't like the way the UI/graphics look/operate. Well, this is purely aesthetics and, if Firaxis changed it for these people, then can almost guarantee that dozens of people will come out and complain about THAT UI. There will probably be around 200 fan-built graphics/UI mods out there for people to choose from over the next month or so anyway, so it hardly seems like a reasonable complaint to me.
(c) I could do X in Civ3 (or 2 or 1) but can't do it in Civ4-thats just not right or, Feature X acted this way in CivY, and it should be like that in Civ4. Well yet again this is purely a matter of taste. Most people LOVE the new religion and diplomacy system, some don't-same goes with city growth, lack of ICS, # of turns etc etc. Point is, just like the graphics and UI, in coming months there will be hundreds-if not THOUSANDS-of mods and variants which can meet even the most exacting pallette. At the end of the day though, it really comes down to the fact that you CANNOT please all the people ALL of the time-be they die-hard fans or 'wet-behind-the-ears' Newbies (the latter of which, I have to say, I really feel like in Civ4-a feeling I LOVE!!!!)
Oh, and of course there is the fact that many of these complaints occured upon the release of Civ3, and so there is a STRONG sense of deja-vu amongst the more seasoned CFC forum members.
Still, if people want to complain about such things here or elsewhere, well that is their right to do so, just as it is my right to point out why I don't think there arguments have merits

(assuming that they DON'T have merit, that is!!)
