Apart from Final Doom, what are the differences between the standalone Doom 1 & 2 and the ones bundled with the BFG edition?
Is it worth buying the standalone games even if you own the BFG edition?

In addition to the differences above, the standalone Doom 2 also comes with the "Master Levels for Doom" mission pack (alongside Final Doom) that is not available on the BFG Edition. Meanwhile, BFG Doom 2 comes with the "No Rest for the Living" Episode that cannot be legally obtained any other way.
