There's no reason why you couldn't use photos for textures. A lot of studios use photos as the basis for textures and paint over the top of them to get the effect they want. 3D engines are becoming more sophisticated and realism is increasing as a result, but if you want to sell a game in massive amounts then you need to make sure that you still support older hardware as not everyone runs the latest systems. There are also time considerations for photorealism in terms of development time. Graphics in games do not need to be perfect - when you look at a still shot of a game, it looks worse than when it's moving. Check out most MMORPGs. The graphics are lower poly than racing games or two character fighting games, but when they are moving around, they are often more immersive (and addictive) than more complexly modelled games. The brain is very good at filling in missing details automatically.

Photo-realism isn't always a good thing too. Check out Rise of the Robots. For its time, the graphics were the best thing ever. The gameplay absolutely sucked though as too much effort was put into the visuals and not enough into the playing/enjoyment side of things. FMV in movies was a fad that thankfully seems to have passed away - millions were thrown at famous actors who were basically filmed as if making a movie. The problem with the games was that it was like watching a movie instead of playing a game, and not so much fun.

Playability > visual perfection/realism

Fun > visual perfection/realism
