Although I do tend to currently have my Fallout 3 marathon sessions when I'm at home, I immediately reduce them to a bare minimum when someone else wants to spend time together. I still insist on having some free time to write, read and ponder the universe, but I don't mind making sacrifices for people.
Speaking of the above scenarios, Scenario 1 is especially frustrating. I don't fully comprehend it personally. Shared beliefs, interests and values tends to make someone much more attractive in my eyes, and I would tend to only outright disqualify them then if they 1. were shaped like an apple, 2. had a mean, control freak, rotten personality or 3. were to lazy to get a decent job and care for themselves and wanted a walking ATM.
