I'd go one of two ways.
If you want "traditional" - stats, skills, weapon lists, spell lists - than I'd be looking at Runequest or some other iteration of Basic Roleplaying, at Tunnels and Trolls, and at HARP, MERP or RM express, and seeing how to distill a game like that down to the bare basics. Probably 4 stats (Physique, Agility, Smarts, Spirit/Percpetion/Empathy), a choice between warrior/scout or spelluser, a basic skill list, and a simple action resolution system.
If you want "modern", I'd be looking at fewer-than-10,000 word games that are also quite flavoursome (eg Nicotine Girls or The World, the Flesh and the Devil) and thinking about how you might use that sort of approach for a fantasy game. Looking at HeroQuest or The Burning Wheel would probably help here (HeroQuest, and the core mechanics for Burning Wheel, might even fit your 10,000 word constraint).
