Roommate drama is the worst and most pointless drama on earth. You have pretty much three options: 1) get rid of the leeches 2) leave 3) sit back and take it Having good roommates is a godsend, and can be insanely fun. I would encourage you to try and find some good ones, because living alone is the defacto for most of the rest of your life (barring, of course, partners/gfs/spouses/etc). If you like Game of Thrones level drama, you can totally play them against each other and find more ideal roommates. Get the other roommate pissed at Luke and gang up to give him his 30 days, then get a new, clean, video-game loving roommate that you can use to ostracize the other one, or, at the very least, create a barrier so that the mess is contained within their room. Don't play nice, the sanctity of home should not be violated, and everyone is always trying to get their cut of the pie.
