the problem is that most of the works I was obsessed with as a kid *did* get TTRPGs (Macross, Armored Core got one in Japan, and Jurassic Park *kinda* had one even if half baked)
Which means I would be, somehow, making a Halo TTRPG because nobody has done that officially yet (there is a fan one)

Okay. You have unfortunately been hit with the curse that makes you adapt a work you liked as a kid into a ttrpg.
What thing are you adapting?
