Interplay can still make a Fallout MMO without paying Bethesda. If I recall everything exactly (without sifting through no mutants allowed forums), Bethesda payed for the rights to release Fallout 3, 4 and 5. Interplay kept the rights to releasing a Fallout MMO and should take control of the Fallout IP after Bethesda releases Fallout 5.
I loved the old SNES Earthworm Jim games, and yes they were some of the hardest platformers ever.
