pretty much the title. i have played most of sierra, lucasarts and telltale catalogues so if you are suggesting one of their games i’ve probably already played it. it doesn’t have to be a copycat, homage or in the same style as these companies’ games either, just that it must satisfy the vague definition of being an “adventure game” and have a good story. thanks in advance, can’t wait to see your recommendations!
EDIT: thanks for your recommendations i couldn’t reply to everyone. i can’t to play (most of) them when i got time.
Free Stars: The Ur-Quan Masters has an excellent story and wordbuilding, and you can talk to all kinds of weird aliens. If you don’t like the ship combat, you can set up the game’s AI to fight for you.
