Ultimately, the person. However, it can not be anyone I know or have known, in fact I would prefer it be someone who doesn't even speak the same language (learn each others languages, that's some time down right off the bat). Since I'm having a hard time picturing both people coming out alive, let alone sane, I would be better off not having to go through it with someone that I already get annoyed with. The discussions (once we could actually communicate) would hold me over without actually killing them for at least another week. Even as I continue thinking about it (waaaaay to much) I still find it hard to picture myself playing video games, even with all of the options in the world for 168 hours (one full week) straight and still wanting to continue. So even taking the risk that being stuck in a room with one person for nearly 9000 hours might lead to a situation best termed lovecraftian I feel that I would be able to lengthen the amount of time before deciding upon the best way to commit suicide in a small room, and ultimately that's the best that I can hope for.
