Neil Gow (designer of Duty and Honour and Beat to Quarters) has just released 'ERA', a game designed specifically for one GM and one or two players: http://www.omnihedron.co.uk/dutyandhonour/?page_id=385 - it's available for pay what you want at RPGNow: http://www.rpgnow.com/product/118877/ERA-Epic-Storytelling-Game and pits classic movie hero types against epic obstacles.

If you have a system, you could use Universal Adventures for the adventures, since you can customize and tailor everything to suit your needs.

Perilous was designed for small groups. There are three adventure packs to support the game plus the adventure that comes with the system, and you can always combine Perilous with Universal Adventures!
