We had a game called "The RoomMate Game" kind of like "The Newlywed Game". The RA asked us different questions about your roommate and you had to get the same answer they picked, i.e. which way do you hang the toliet paper, so it hangs down in the back, or in the front, silly questions. It was fun! My friend and I won - even though we were in singles. We thought it was funny we knew each other better then any of the room mates and we didn't even share a room!
At the holidays our RA wrote to our parents and had them send holiday gifts for us to him, then he handed them out. It's too late for holidays, but maybe before finals? I'll email my old RA and see if he remembers - it's been a LONG time!!!
