This isn't the first time that a game has appeared in Microsoft's Xbox LIVE Marketplace ahead of its launch. And it's not the first time that, even if you had the required amount of money to actually download that said game, you wouldn't be able to. Digitally distributing games for review isn't a new concept, but it definitely does add something quite entertaining to the whole mix. That's exactly what's happening with Halo Reach right now, which you can find in the LIVE Marketplace right now, ready to download. But, as usual, there's a catch.
