3 4 and the Telltalle series... you won't miss much. But 1 and 2 are why this game launch made it even to HN.
Fair enough about the others, but that’s a controversial opinion about 3, which is critically acclaimed and a classic for anyone played it as a kid in the late 90s. It only gets criticised because Ron Gilbert wasn’t involved.
The voice acting cast from it are nearly all in Return, along with lots of references, so it’s canon for Gilbert purists now too!
Was it the one with monkey combat? And time travel? Or time travel was in 4...
Curse was the 2D-cartoon one with demon LeChuck, Elaine turned into gold statue, chickens and rollercoaster of death.
