Halloween is great. It's the only day of the year you can get away with dressing as the bug-eyed rabbit from Donny Darko and not immediately be sent to a crisis center. Also, it turns out that it's also a great holiday to save some cash on video games. 2K Games has joined the price-cut party with some stellar deals of its own, all of which are slated to run into this weekend. And if you decide to buy, they could possibly occupy the entire thing. Games like Civilization Revolution are time warps -- you boot them up and all of a sudden it's 4AM .

Here's the full list of what 2K is offering on the cheap. Take note that Sid Meier's Pirates, which is another great time sink, has hit rockbottom sales-wise, too:

• Civilization Revolution - $6.99 ?�$.99
• Civilization Revolution for iPad - $12.99 ?�$1.99
• NHL 2K11 - $3.99 ?�$.99
• NHL 2K11 for iPad - $4.99 ?�$1.99
• Sid Meier's Pirates for iPad - $4.99 ?�$1.99

I've been playing Civ Rev on my iPad for a long, long time now, so I've got zero problems with telling you to buy this thing now. Despite being a simpler version of Civilization proper, Civ Rev's easily manageable strategy components are deep, compelling and satisfying. Give it like an hour or so to learn and then wave goodbye to your fun-fun iPad free time for a couple of months. Also, this is the biggest sale it's ever seen. I mean, it's eleven dollars off! Definitely jump all over that while you have the chance.
