If you've read all the other GOG.com reviews, you'll already know that BG&E is a wonderful game, and that you should buy it. What you're probably trying to decide is whether to buy the original PC version from here, or to buy the HD remake on Xbox live arcade for 800 points. Essentially, the HD remake is a tweaked version of the original PC game, which ran in much higher resolutions than the PS2 and Xbox versions anyway. The additions include adding achievements and Xbox live scoreboards. The HD remake also works a bit better with a 360 joypad compared to the PC version, but if these are not important to you, I'd definitely stick with the GOG.com version.
A lot of people have already written about the game itself. I just wanted to add that the folks at Fresh 3d have done an awesome job reengineering the game for version 1.1. The game runs smoothly in 1080p, and is a joy to play on the xbox gamepad. A perfect excuse to get back into this fantastic gem from the past!
