Glory to Rome because I play Race for the Galaxy a lot alone without the solo variant and have a great time. Reviews say that GTR is even better. Is this perhaps too much of the same?
Roll Through the Ages: The Bronze Age because it is a dice rolling game and I don't really have any in my collection. Seems better for me than Stone Age that seems to run a little long but could be played solo - I would play 2 players to the best of their abilities.
