When it comes to a game like Civ, then you'd definitely be in the minority. With console games displaying near-video quality in their titles, developers can't afford to cut that many corners in their releases. It would be a quick way to assure their bankruptcy. I don't even consider the graphics in this game to be all that great. They're adequate, nothing more. Compared to games like Oblivion and NWN2 they're pretty basic, but that's all that's really required for the game. And it's not really a problem playing the game with them if you have some half decent gear.
The civfanatics forum posters are already a minority.
I'm not sure what near-video quality means to you, but it seems vacuous.
If you are saying graphics are very realistic, just remember it's all relative. Ten years ago 3D graphics looked realistic. Five years ago graphics looked realistic. There will probably be a point in time when developers start to realise that people care more about gameplay than graphics. The only reason games are so darn expensive these days is that so much goes into the art side of the games. I remember back in the day when you could pick up a snes game dirt cheap, have weeks of fun with it, just like any modern game, and it had simplistic graphics.
There is a reason people still do things like play board games and card games. It's not just the social interaction, but the gameplay is obviously good. If the never-ending pursuit for more detailed zombies, with thousands of particles created when you blast its head off etc., and point and click shooting is the pinnacle of gaming, and is called progress in gaming, then I'll stick to civ1, civ4 and any other game where graphics were not so ridiculous. Advances in game graphics may be an interesting technical feat, but I don't think it overall does anything for gamers overall satisfaction in games. Do games provide more enjoyment than they did 10 years ago? I think the only games where you can argue this are ones that try to be very immersive - eg. flight sims, driving simulators, ... pretty much any simulation games.
