I get stingier and stingier the more Steam sales I see. You guys are saying buy MGSR, but I look at the price and think, no way in hell. Maybe two or three years ago I'd bite at a $15 game. Now my maximum is $3, my comfortable purchases more around $2.
I am okay with super low prices as impulse buys, because once you start going that low it doesn't feel so bad having them sit in your library unplayed. If you get Rising now, and don't play it until after Christmas, you might have blown the opportunity to get it for $10, maybe even $5.
