Re: ps3/xbox 360 missing many "edition" of games

ah i see so a lot like when tracking down DLC, not a lot of info or lists out there to check what would.
an its all good, i woudlnt know what id want without seeing the games an checking the content on each anyways.

I don't know which games have unique bonus disks off the top of my head. I only found the Gears of War listing because you explicitly said Gears of War in your post. Not all discs that could be considered "bonus" content are explicitly categorized as bonus discs, either. For example, the Bioshock Infinite Complete Edition bonus disc is not labeled with the "B" icon despite having "bonus disc" in its name: https://vimm.net/vault/88072

That said, going through the 360 games with "bonus discs" enabled, I did find two more with the "B" icon:

Dead Rising 2 Zombrex Edition Bonus Disc: https://vimm.net/vault/80916
Street Fighter IV: Ties That Bind Bundle Bonus Disc: https://vimm.net/vault/92363

If you're not looking for anything in particular, however, it is hard to know if anything is missing in the first place.
