Games you regret buying?

I just got into the hobby and have bought a few games like Final Girl, Core Space, Maladum and am still looking for a few more to add to my collection.

There's a lot of threads with good games recommended, but has anyone bought one that was hyped or looked good and just wasn't feeling it?

edit: thanks for the answers! most regretted seems to be Gloomhaven or 7th citadel
