Doom, Doom II, all Final and Ultimate Doom content, and a Doom 64 port ala the Doom 64 total conversion that's available. All widescreen on console instead of 4:3. Freelook added optionally ala the PC mods. Higher resolution, but otherwise the same as ever.
Doom 3 port with flashlight dynamic shadows readded (as the forthcoming patch will evidently do,) Lost Mission, and RoE. On-armor flashlight and original D3 flashlight as a togglable option.
Co-op implemented on all of them (64 being a possible exception.) All playable directly from the in-game title screen on console unlike with BFG Edition.
I'd gladly pay full retail price for such a package. Call it "Doom: Complete." Anyone else interested in such a product?
