I didn't buy it (I'm way too cheap), but the highest price tag I've ever seen on a game was $79.99 on Mortal Kombat II when it first came out. Of course, that was at a regular store, like K-mart. I don't deal with collectors, so if there are any valuable, rare, etc. games that go for big bucks, I wouldn't have seen them, nor would I consider them to really count.
