I am interested in purchasing both games again to replay them.
Does anyone know the cheapest I can find them at the moment. I really wish they included Dead Space 1 with 3 the same way the did with Assassins Creed: Revelations.
Which versions? If you're looking for the PC versions, I'd look on the Steam game trade thread. For the console versions, your best bet is Craigslist or eBay.
