This week Julius and I discuss solo gaming and controlling more than one player while playing solo.  This refers to playing multiple characters in a co-op, such as Pandemic but also playing opposing sides in a multiplayer game.  There is so much more we could have said but we kept it short at just 35-ish minutes!  We mentioned a bunch of games.  I'll have to be honest though.  I didn't think to write them down so I will list the ones I remembered.
Pandemic (BGG)
Pandemic: Iberia (BGG)
Pandemic: Reign of Cthulhu (BGG)
Pandemic: The Cure (BGG)
Pandemic: Rapid Response (BGG)
