I don't often post reviews online, but I was so disappointed by this product that I was moved to make an exception. Three of the four games (Lumines, Geometry Wars 2, and Bomberman) are included on a disc. The box includes a code that allows you to download Ms. Pac-Man from Live. For people who have hard drives and Xbox Live (which really should be everyone), this latter solution is the only one that makes any sense at all. You dial in the code, download the game, and it's as simple as any other XBLA game from there on out. The other three games all must be played off the disc - it does not permit you to play them like you would regular XBLA games. However the software code is largely unchanged, so that the games themselves don't recognize they are being played off a disc. Bomberman simply doesn't work - it tries to force you to download an update of the game, but because you never downloaded it in the first place, the "update" would cost the full $10, and it won't allow you to play without the update. Lumines and Geometry Wars 2 are at least playable, but I don't know if Lumines DLC is compatible. That's iffy at best and I wasn't willing to risk it. I will be calling Xbox support, which isn't something you should have to do minutes after opening the box.
In sum: it is more of a hassle than necessary, poorly thought out, and one of the four games simply doesn't work. I am extremely disappointed and cannot recommend this product.
