It's not about the graphics or how old a game is it's all about the content. No sensible adult would allow a child to play X-man still today due to the pornographic gameplay. The ratings system we have today is just a guide to what parents can expect to find in a game and is pretty worthless since everyone I know have no clue what this or that game they bought for thier kid is rated and none of them prioritize the game rating over what the kid wants. If your 4 year old wants to play GTA it's your choice not the ratings board.
