I would add the following as "solitaire exclusively"...
- Fields of Fire 2nd edition.
- Enemy Coast Ahead series (Doolittle Tokyo raid ect).
- Lock N Load Tactical with the solo module.
I still think it´s best to play normal games in a hot-seat mode, if there´s no hidden info in the system. Systems with "chit-pull" work pretty good for hot-seat gameplay.
