Now that this game has been out for a bit, you can get all 7 games for the price of 4 on disc. So instead of spending $10 (800 MS points) on each game (which to me is a good deal), you can get $70 worth of games for $40. That's a great deal! If you find 4 you like, might as well get the disc for the extra 3 (and extra 600 points!).
These games are fun, either by yourself against the AI, but definitely more so with friends, family, or online (where I just lost a game of Sorry! by one turn... ooh, dang it, I was holding that card!!). The controls are a little funky, but they work fine, and there's no rush... these are family board games after all.
But for us achievement hounds, I'm forgetting the best part... 1400 points for $40!! You can't beat it (unless you're borrowing your friend's copy of Avatar: The Burning Earth)! Plus, a lot (if not all) are relatively painless. The games are fun, so winning a bunch isn't a chore (not really). A lot of the rest you can win by playing with a second controller.
Yes, it's a family game, but these are all classics. Not quite Rock Band party excitement, but still worth the time. And 1400 points for $40. :-D
