The worst part of roommates is that they never have the same appreciation/consideration for your stuff as they do their own. So they may play your games and toss the controller or leave CDs out of the case.
So if it were me in this situation, I'm taking a rugged and little PCE/Core system and 3 HuCards:
- Gunhed/Blazing Lazers
- PC Genjin 2/Bonk's Revenge
- Bomberman '93
My favorite three games overall, CD or Hu, actually
But if I was brave enough to bring the Duo:
- Gates 4-in-1 (gets me the Bonk games, a high quality shooter, and the multiplayer classic Bomberman)
- Lords of Thunder
- either Gunhed or Kyuukyuu Tiger
Since it's school, no long RPGs for me. Too easy to get sucked in and blow a shit ton of hours.
