I just recently unbolted and sold my bolted down games STTNG and LOTR. I had them both for eight years and claimed they would never leave, but I needed to shake up the collection and they were getting played less, so out they went. I think if your wealthy enough to have the space and cash for a large collection, then you can truly have games bolted to the floor. For me at 5 games max (sorry I'm not sticking games in front of doors ) I think my "bolted games" had a good run. So right now the supposed bolted games are TWD premium and IMDN premium. Maybe MBLE will make the list.
