I have a reasonably powerful Mac, and I play CivIV on it. However, there are very few games available for use on Macs, and I do most of my gaming on consoles anyway. Playing games isn't something that I do very often on my computer (I only really have four games that I use it for most of the time: CivIV, Age of Mythology, Age of Empires III, and Knights of the Old Republic). If I spent more computer time playing games, I wouldn't be using a Mac. As it stands, I'm more comfortable with a Mac for everything else that I use computers for, so I'm not getting a PC anytime soon. Besides, most of the games that I like best are console-only. I'm sure PC snobs will state that this makes me some form of inferior being, but I rarely take other people's opinions seriously, especially not those of snobs (I hate snobs, but I like to have them around. They're so much fun to hate, and it doesn't really count as bigotry). I know what I like, and I stick with it until it ceases to entertain.
