In the 2020 game Doom Eternal, there is a way to play both original Doom games, Doom 1 and 2. Since the game (also known as a WAD, or a megawad) is made by one of the founders of id Software, as well as Doom itself, it would be great to be able to play Sigil in the game as well.

Along with the soundtrack created by Brian Patrick Carroll, known professionally as Buckethead, which costed €6.66, as another add-on. Separate with the regular Sigil as it came with a MIDI soundtrack, which was free.
