I love Dr. Who. Here’s a solo game that lets you help the Doctor save the universe. From the game description:
‘Doctor Who’ is a paragraph based solitaire story game. You read various numbered sections one after another but the sequence of the paragraphs is determined by rules and tables. Each describes a new situation, or provides rules about the choices and actions you can make. There are plenty of events and situations, so each game will be a new, fresh experience.
Free for the downloading, Spellcraft and Swordplay is a professionally done “old school” fantasy RPG.
Mephisto is a free print and play game in which you are an adventurer collecting the souls of monsters in a dungeon to fulfil a deal you made with the devil.
Dark Dungeons is a clone of the old school D&D game. There’s been a real renaissance in the retro style RPGs, and its one I welcome after all those years of angst ridden vampires and new-style gaming.
Intructables has an article on making a “spiked barrier for a Rohan gaming table,” but this sort of palisade would be great for a huge variety of periods and scenarios.
