So I've got a question for all of you: should I get this game? It's part of a BundleStars bundle, and we all know I have a hard time resisting those, but I'm trying to limit myself to bundles containing mostly games that I will actually play.
The gameplay seems to be centered around combat. Is there more to the game than hacking at enemies from horseback? Is there a good story, or at least an interesting world to explore? Can I build a house and things like that? Basically, does it offer me anything I don't already get from Skyrim (and Morrowind)?
It's a different kind of game than Skyrim/Morrowind. Yes, it's pretty heavily centered around combat, albeit of a different sort. Think of it more like an RTS with a twist - that being the fact that you can yourself take part in the fight. While there is an RPG upgrade system, the actual firepower upgrade lies within recruiting and upgrading your troops.
There isn't a story at all, in fact! It's basically a sandbox in the more strict formulation of the term - you are thrown into a world, given a bunch of things you are able to do with it and told to basically do whatever you feel like.
There's no specific endgame goal (in an unmodded M&B and Warband, this is) unless you specifically choose to pursue one, for example becoming the ruler of the whole world with your own kingdom, loyally supporting any of the existing kingdoms, leading a revolt to put a lawful ruler to the throne (for example, the wife of the late king, overthrown by the king's brother after his death, or a patrician who would have been elected to lead a republic if not for the current king blackmailing the electors).
Or you can, for example, decide that you just want to make X amount of money, and you can just run from town to town, buying enterprises that make you money or buying trade goods and selling them at a profit. Or maxing out the village relations with every village in the area by doing quests for them. Or whatever else.
It is also extremely moddable, with the majority of the existing mods basically porting it to another setting, like Napoleonic era, Dark Ages Britain or even, for the first game, fucking Star Wars universe, although a notable few add new features to the mix. I, for example, once spent a week roleplaying a bounty hunter in a Western mod for the first game, taking out bounties (it's also a thing you can do in both games unmodded, albeit it's taken from a lord along with different possible quests) and hunting by day, then returning for a game of blackjack (a feature in the mod) by night.
As for the 'is it worth it' well, I cannot really tell if it would be right up your alley, but me, I have around
seven hundred hours clocked in total in the original and the... basically upgraded rerelease Warband, so yeah.
Also, important factor - which game is it? Both M&B and Warband? Either? The latter has a slew of upgrades in graphics (most notably the clunky-ass combat animations and shader support) and features (the aforesaid 'your own kingdom' thing among them, although there are ways you can handle this in the original, along with the very much alive multiplayer) and mod-makers tend to make most of the stuff for it nowadays, HOWEVER, the original has a number of very good (I dare say - better) ones which, for a really dumb technical reason, are not exactly forwards compatible unless you make a simple hack.
Also, wow, wall of text.
