I do now and then, but it's pretty tough to get really close when I do, as most games don't feature the creation details I would like...if they DID a game would pretty much be equal to having Maya or something built into it * lol*
seriously though, I find some games I love " like mass effect" which has potential for a great builder to have a really limited one...sure it looks nice, but the down side is that they are still a combo of presets, thus limiting the outcome...
I see some games with great face builders, so recreating my face is one thing.. never see good body building features, atleast not as often as I would like. I can always get my face anymore or close enough, but my body type is not one that fits most defaults for females, Im tall, " nearly 6ft" and athletic build and quite busty ( some games that allow altering to the bust make me think the developers have NEVER seen a womans chest before in real life, as they look scary when enlarged even to " more realistically natural standards of large") I know it's mostly because they keep the models fairly simple, and the control points lower to save room, and ease, but sometimes a game comes along that I may want an identical match. and if your a woman, hair options can suck quite often too..
but again there are some games that do break the mold and have really good altering ability that look realistically rendered...
and though I lost interest in the games and the spectacle of it all.. WWE games traditionally have had really good character creation even going back to the 64 bit gens.. and though they are not always the top line, they have been pretty consistent and offer alot of goodies to help perfect the character, and I think some studios should take a look and atleast try and emulate that alittle more
