I've never noticed the issue with Risk, though I noticed it more often with Diplomacy the summer I played it multiple days a week (it was at a "pre-college" camp thing for academically inclined students). We were stuck there for 5 weeks with each other, and it was actually a good experience because it taught us to overcome how we felt towards each other. So alliances would change regularly each game, which was nice, and we all learned how to move on after and go do something else...usually Ultimate.
