Just to maybe clarify my choices for the poll:
- Batman - not very probable, but a series that received high praise. Not a long standing franchise (gamewise, not the IP itself) to attract big backlash, and not a standalone system seller, but certainly on par with TR.
- Dead Space - currently dead. Would not cost much to have their friends in EA make an exclusive game, or even sell them the IP completely. A well made reboot, marketed properly could be a big spring system seller
- Fallout - a real long shot, but also a game that could actually bring the biggest return on investment. 9- month time exclusivity for PC would do wonders during holiday 2016 (Gears in September, Fallout in November)
- Madden - certainly the game that wouldn't cause much furor from PS fans, but would be a great August seller.
PES - this exclusive could make them.a competitor in Japan
Resident Evil - my choice. We often hear Capcom being at the edge of bankruptcy, they might need some upfront cash. A multi game deal, handled properly, could be huge.
Saints Row - another franchise that is probably defunct. Brand name is still popular, and a step in the more serious direction could resurrect it. While it may not compete with GTA, it could certainly battle for #2 with Watch Dogs, Sleeping Dogs or some other dogs.
I also left out many possibilities in IPs that are not ass established, and that would actually come cheaper, but I wanted to go this route due to TR purchase.
Certainly titles like Red Faction, Just Cause, FEAR and similar would be good additions to the exclusive library.
