Unfortunately, many developers are more concerned about making games look pretty in screenshots, rather than looking good in motion. As I previously mentioned, Bioware is guilty of this with their KOTOR and Jade Empire games for Xbox. Those games all had some absolutely stunning screenshots, but were disappointing in motion. The framerate was erratic and the animations were bizarre. I laughed out loud at Jade Empire. There are some scripted scenes where an NPC has to run from point A to point B but there might be some obstacle in the way. The NPC will sprint full out for about 2 feet, stop abruptly, rotate a little, sprint 3 more feet, stop, rotate, etc. It's hilariously bad, and in those moments it totally ruins the immersion they were going for.
