I voted Rollergames, TZ, and Spider man but I thought Indy was Indy 500. I probably would switch out Spiderman for AC/DC though.
It would be risky getting rid of games you love for games you haven't played. I would be tempted to find someplace to stash three games as others have suggested and then after owning the three new ones for awhile you may have a clearer picture as to whether any of those three are keepers. I've heard universal praise for AMH but RZ sounds brutal and Hobbit may get tiresome after awhile. It would also be a good idea to get rid of games that are easily replaced if you decide you want to bring it back. Good Luck.
