'Tis a flash sale for the next seven or so hours.
Fire & Sword any good? I remember holding off on it a while back because people had a bunch of issues with it.
If you like muskets it might be your game. Although supposedly mods with equally good ones exists.
It also has some actual storylines in it, although you need to follow a step-by-step guide to activate them and not fuck them up.
It doesn't bring that much new to the table (I think the sieges and fief are a bit better as well), but it's been worth my money.
If you want guns it might be a better idea to get Warband + Napoleonic DLC. There are organised events with 100 players, and it's easy to get in a squad of some sort. It's good fun!
I never liked multiplayer in this game.
The melee controls just feel really clunky, after I had been spoiled by the dueling mechanics of the Movie Battles II mod for Jedi Academy.
F&S is not a sequel. It is more of an official mod with a storyline.(Or I guess limited expansion...)
Plus, if you want guns, there are mods that are plenty good and have guns in em.
In short, the base M&B Warband is good enough, since you got mods. None of em require F&S to work. F&S don't really add much overall, but 2 dosh ain't too bad for it. It is your choice.
