Probably the most popular mod for the original Mount & Blade v1.011 - now also for Warband!
This is a pretty amazing mod. The work done has been paid off and the results are fantastic! There are still a lot of issues though, that keep it from being the best. Fans of large battles will be severely dissapointed unless they disable both corpses and ragdolls unless they have a high-end computer. Occasionally I would see error scripts runnning, like when I tried to recruit umbar corsairs and instead got black numenoreans. The intro trailer has caused my game to crash about 3-4 times. Overall a great mod, just needs work.
