I think video games are a great way to get an idea of compatibility. I like Resident Evil 5 to gauge compatibility. I know it sounds silly but my ex-fiance was not a gamer yet we beat the game on the highest difficultly. We also had an easy time with Army of Two. The ex I had last, whom was a gamer, it was a thorough struggle. It's fun to see how well you work together even if it's a game.
