"If you owned DOOM (1993) and/orDOOM II, you'll receive DOOM + DOOM II for free."

But the BFG edition has DOOM and DOOM 2, so please also add the possibility of having it free for those who have DOOM 3: BFG Edition.

DOOM 3: BFG Edition is still a DOOM 3, not DOOM or DOOM II. Old games - is just bonus content for this Edition.

"If you owned DOOM (1993) and/orDOOM II, you'll receive DOOM + DOOM II for free."
You must have DOOM I Enhanced and/or DOOM II Enhanced versions to own this for free.

At the same time, Enhanced versions of DOOM and DOOM II owned for free to those who already purchased the DOS versions of The Ultimate DOOM and DOOM II.
