Let me suggest Advanced Fighting Fantasy Quickstart:

It is a quick and simple d6 system, that originates to the classic Fighting Fantasy solo gamebooks and that leaves the door open to rules customization and adaptation to specific settings. The loveliest aspect is that you can create a new character, literally, in 5 minutes.
The only critical bits missing in the freely available Quickstart document are characters creation and, in part, magic. You can find them easily in the public threads of any AFF game currently on RPoL.
