Now people who want to enjoy this DLC must either rent the game multiple times, or purchase it. Since local rental stores (esp. Blockbuster) are going out of business, Redbox and other kiosks are the only thing most people have access to, but Redbox has a tendency to cycle out old games quick, so I doubt RE:ORC will still be available for rental in ~3 weeks.
I'm beginning to think Capcom knew this game had "rental" status written all over it, so they planned DLC in advance. Knowing the DLC "Street Fighter x Tekken" controversy, it's not unrealistic to think they had this content made well in advance at the Capcom offices, but that's for another topic.
I'm personally going to wait until all the DLC comes out, then buy the game used for ~$20. I figure the DLC will total at least $10, so I need to buy this as cheap as possible.
