I highly don't you'll even use the extra features of the Media Center Edition. If its the same price than sure why not, but if your just looking for an OS, home is basic and has what you need, neither will hinder or be better for your gaming. Just install all the updates after you install.
I just looked at what MCE adds and it lists Media Player 10 and Directx 9. Wow, they add all that? Being that both are free. I guess if you want the themes and the really crappy Movie Maker MCE would be a choice. Its only about 10-15 bucks more than Home Edition.
