Actually I'm breaking tradition for Skyrim.
My video game purchasing tradition is usually:
1) Wait two weeks after the game has come out.
2) Read reviews on game.
3) Ask on a forum what other people think of the game, and find out what games it may be similar to.
4) Go to YouTube and take a look at the game play.
5) If after doing 1 thru 4 I still have an interest in the game, buy it.
For Skyrim ..... I've already paid for it
