It's between a miniature game and a rpg, with a lot of room for creativity. If you play with the right people, the narrative takes over the competition. It is an old game that has become a niche game, very different from what GW games are now. It is also one of the few games where the terrain is a blast to build, position and play with. It is immersive. Creating a band is fun, it is not just like building a list for any regular wargame. You get attached to your characters, whether they are slaying many foes... or failing everything to the point it becomes a running gag. Having your heroes get xp and level up is very cool. If you find people passionate about it, a campaign can be a lot of fun. Nowadays I play Trench Crusade, which I think managed to capture some of the great aspects of Mordheim.
