I think that Socrates, Plato and Aristotle together would find it hard to convince me how these smudgy, floating rivers that cast shadow over their own bank in Civ V look better than rivers in Civ IV or Colonization.
I mean, look at this. It looks like a bad Photoshop job.
And in contrast, this is the river from Colonization. Sharp, crystal water through which you can actually see the rocky river bottom, and you half-expect a fish to pop out of the water if you zoom close enough.
Hell, I'm no high-detail graphics whore. I actually prefer simpler graphics in Civ V than in Civ IV, I find it rather stylish. I don't miss animated trees, mills or anything, in fact graphics on the ground is a lot better here. And in the game like Civ, graphics should be secondary to gameplay. It really should. What's bad about this is that it simply sticks out so much, you can't help but see the hideous ugliness of the river that looks like it's been drawn by a 10-year-old in Paintbrush. Hell, rivers in Civ 1 from 1992 had more life that these.
I can only explain (and hope, hope and pray) that this was an overlook by developers, although I can't see that being the case. This is so awful that it makes it impossible to miss on the very first look upon the world, or to ignore subsequently. How the hell can ocean be so gorgeous that you want to make a dive into the monitor thinking you'll end up swimming in crisp azure-blue fluffy waves, and yet the river and their deltas look like sewage overflows?
