The second is Prophesy of Pendor, which is far from simple and altogether brilliant. The first is the simplest of mods, all it takes is a rejigging of configuration files, so if you like flames to go with your swords, you’re in luck.
I prefer it to With Fire and Sword but that may be partly because I’ve not really given the newer title a chance because I’m playing Warband with two lovely mods that I can’t imagine doing without. Mount and Blade: Warband is about as fine a Mount and Blade game as I’ve played to date.
