Reach still has my favourite multiplayer of this generation, I would say it warrants at least a "good" (though I'd go with AWESOME). I'd snap that up in a flash, but alas, no stock. :'(
Additionally, the headphones in the SR3 pack are trash, in case anyone was wondering. I only got to use mine for about a day, then just stopped. No idea why. Next, I forgot the batteries in for a week, and the next time I tried to get it to work... Boom. Buy it for the game and DLC, not the headphones.
