That's the main reason why I don't like most games nowadays, they're way too realistic.
I mainly play games to get away from the real world and relax, and playing a game that tries to mimic the real world as good as possible doesn't exactly help with that. No, give me some colorful graphics, characters with quirky personalities and fun yet simple gameplay (I don't need to have the ability to modify my weapon with 9001 options, seriously).
This is why I'm such a fan of Nintendo (up to the GC anyway, Wii is kind of bad), they have all these great titles that fit the games I prefer for their systems, like Mario, Zelda, Banjo-Kazooie and hell even a "dark" game like Conker's Bad Fur Day had colorful graphics!
