I've got a pretty respectable collection, but I don't get to play as often as I'd like with other people, so I play solo games a lot. However, many of the games in my collection weren't designed for solo play, and I've either created solo variants or played with user-generated solo variants I've found on BGG.
Do you have a favorite non-solo game that you like to play as a solo variant?
The ones that stick out to me are:
Dragon Brew (although there is now an automa available)
Above and Below
Dead of Winter (TONS of solo variants and scenarios available for this)
What are some of your favorites to explore?
