What are you looking for exactly? Mount&Blade is quite a bit of fun combat-wise (can be really repetitive, AI is predictable but also rather deadly). I've won battles nearly single-handedly by having my forces line up in formation while I go after two dozen cavalry with a Greatsword or a lance of some sort (my favorites are the military scythe and the ashwood pike, actually). The combat's more based around skill and not getting caught vulnerable. Then again, castle sieges are a little bit unfair. Defending is either really easy or really hard. I've had good "luck" defending as I tend to do a little exploit that the AI simply won't, which is to force ALL my troops outside of the castle. For some reason, that gives me a huge advantage and they typically get run over.
