This is an idea I have as a web series, but I imagine I will probably never get around to doing it.
However, it is a nifty idea, and I thought it might entertain you to read about it.
I call it "Boss Battles in GZDooM". What I would do (if I did it) would be to roughly replicate boss battles from various movies and television shows using GZDooM. Basically, I would create the environment as a level and the boss characters as DooM monsters, then play as the hero character and record the battle. The recording would then be uploaded to Youtube.
What battles could be replicated?
I am not sure, but here are some ideas:
Bladerunner: Deckard vs Roy Batty
Aliens: Ripley vs the queen alien

Any other suggestions?
