It's a very charming system - which made me think a lot of Fighting Fantasy, Dragon Warriors and HQ.
It might be good for a fast dungeon crawl weekend. It lacks figure movement rates - but it would be easy to adapt some of the stats to a number of squares. Spells are based on a difficulty roll. Enough scope for different weapons and armour, also a few random treasure tables.
I adore systems like these because I feel free to create anything I want (and I never had the guts to go "home-brew"!)
Warrior Rogue Mage was a complete freebie - I've only dipped into it and seems to make quite a bit of sense -like some other systems it lets the players invent specialisms appropriate to the game/setting/genre.
I'm still not sure about fire arms in fantasy games ...
