Unless I grossly misunderstood the description, Doom 3 BFG says it includes Doom 1 & 2. My question is, what is the difference between these bundled copies, the Doom 1+2 bundle, and Final Doom?

IIRC the BFG edition's copy of the originals was censored, with the first aid sign being taken out. But it has No Rest For The Living included. It also has much lesser compatibility with mod content, which is a huge issue.

I'd say get both.
