I'm a gamer lol
I play a lot of RPGs, which are VERY time-consuming. While I spend a large amount of my time playing games (like 8+ hours?), I don't let it get in the way of anything. I still make it to church, spend time with God, make strait As, ect. I believe in the near future, my time won't be as plentiful as it is now though lol.
As far as game content, there's a certain amount I will allow. For example, the blood and language of games such as Bioshock and Call of Duty can easily be ignored without following the examples, unless you have a tendency towards violence or cursing yourself. I think that games involving sex are universally dangerous, though honestly it's especially bad in me. Also, games with a TON of unnecessary cursing like Saint's Row and GTA should be avoided.
I play competitively (not professionally though), so I'm more focused on gameplay than anything else. I can easily ignore the trash, but I can't say that this applies to everyone, and you should learn your strengths and weaknesses and be careful ^_^
