Firstly: Not a "Games as art" thread, I think we have one of those already. But a thread to discuss the visuals in gaming, the good, the bad, the ugly and so on.
Here's the article prompting me to start the thread:

A decent article about how keeping things simple, or at least visually consistent, can be much better for a game than creating a game with intricate touches of detail all over the place. Something I can certainly agree with. I know and hgely appreciate the reason why most games have explosive red barrels. Cos we know as people, and especially as gamers, that red barrels go boom. And we know that in a split second. Same as you know you can crawl through vents and small units about 5 foot off the ground and sticking out the wall are going to recharge us or similar function.
