Sorry about this but you're wrong. There is DLC. Both "See The Future" and "Knothole Island" cost extra unless you buy the Platinum Hits version.
Technically speaking if he did get the Platinum Hits version then the DLC is on the disk so I would say it still counts.
The topic title says no DLC. Even if it's included on some discs it's still DLC. But if we can break that rule then I say. Fallout 3, Fallout New Vegas, Borderlands, Red Dead Redemption, Grand Theft Auto 4, and Bioshock Ultimate Rapture Edition.
