Could you request a refund if you didn't really know what you're getting into or dev's behavior?  Example: You bought a game and you have some ideas what the content might have, but didn't fully grasp till you actually bought the game and played it and didn't like the content the game have.  Or if you already knew what you might be getting into, but didn't know of the dev's bad quirks until you bought the game and read on some of the things that the dev had said; within the game folder or somewhere else.

Sorry for my poor grammar as I am not good with grammar despite English being my only language.

Update: I finally got my refund and it seems you can, altho having spent my time within the community I realized it wasn't as bad I made it out to be.  So I would rebuy the game but it will be on my low priority since I feel bit bad refunding.
