Robert, do you realize that what you are saying conflicts with the Sacrament of Marriage? Think about it.
Blackspur, I think it depends on your motives. If you are doing it for fun, and to test how good you are at the game, then I see nothing wrong with it.
The things to watch out for are the desire to
beat others (as opposed to just the desire to win), to feel superior to them, or to have something to brag about. That would indicate the wrong kind of pride.
If the games tempt you to feeling violent, or to think badly of women, you probably shouldn’t play them.
I’m not saying you will be tempted, or spiritually damaged, by the games. I’m pretty fond of the Bard’s Tale, and his morals are none too good. And I also like Diablo I and II, and about all you do there is kill the bad guys. (I haven’t tried III yet.) But I recognize them as fantasy, and thus don’t let them affect my morals. Most of the time, I play Hidden Object games, and most of them involve ghosts, witches, and vampires. Nope, still not affected. I even read the Harry Potter books repeatedly, and guess what? I haven’t become a satanist.
Remember that Paul preached using images from sports. Getting to Heaven, after all, is winning the battle against sin!
Good luck!
