You should note that you do not have to go about it this way (as people will need to have a memory stick or spend more money). Make it clear that they do not have to have all these GB's, they can play on the 2 separate discs that come with Halo 4. You put in the campaign for campaign, and the multiplayer disc for multiplayer, however if they want to access multiiplayer from the campaign disc, then they can utilize this alternative. I personally am not going to lash out extra money for more memory when I can just use the disc that is needed to play. I don't mind switching discs, that takes like 3 seconds out of my day. Now if you have an extra memory stick laying around, sure. But don't go waste money on a memory stick to incorporate multiplayer on he campaign disc if you're not that lasy as to just change out discs. I will change them out based on what I feel like playing. Not a big deal.
