Mount & Blade: With Fire & Sword OR Mount & Blade: Warband ??

Warband is better

Warband is better.. If you want guns, you could always get mods. Or the dlc. Warband has much more active players afaik, and its just better imho.

Warbrand

From what I have heard, Warband is better by a considerable margin.

Jumping in on the warband wagon (param pssss). It really is better.

Warband + Napoleonic wars

Warband. WFAS is fun, but it's not as good as Warband is. Definitely get Warband.

Definitely Warband, fantastic mods for it too.

CLEARLY WARBAND ! yeah i use capital letter for important things like that or saving life on the internet ... you know ...

Warband.

Get both. Just Warband if you REALLY can only get one. Warband has by far the most mods and the least bugs.

Not sure if mentioned before: Warband!

Warband, there are also awesome mod for it, but if you can you should take both of them, I have them both and I've paid very little (around € 9.99) and both are very beautiful and fun!

Warband, no contest

Both if you can. Warband if you can only get one.

Warband....if you want firearms play one of the many mods for warband that include firearms. Warband has all the mods that make the game from good to awesome.
