I feel this way about a lot of games, to be honest. There's so much side-quest filler that feels like work to me (a first play through of one of the Far Cry games had me crafting a wallet or some such nonsense) that it's become quite off-putting. As a teenager with nothing but time, I probably wouldn't have cared, but as a grown man with a full time job and little time to spend on video games, the last thing I want to do is feel like I'm working.
