The cRPG mod for Mount & Blade: Warband can be called one of the most ground breaking mods ever!
Especially because this mod features experience and level upgrading and lets you buy your own items. I will explain most of the features and hows further on and you can see for yourself in the screenshots and play for yourself of course!
The cRPG is mostly a Native based mod for Mount & Blade: Warband compactible with most versions, so also V1.125. This also because the cRPG mod is still in serious development, but is still very playable.
The system works as follows, you register at a website, you can equip your character with certain items, and buy new items in the webshop when you received enough denars for it. Also, you can upgrade your character with different skills and abilities, so you can specialise them in a certain weapon for example.
When you come to a server of cRPG, you can join a faction, but you will be able to choose from your purchased items on the website of cRPG. But describing this process would be to long. I will post links in which you can find more information about logging in and playing cRPG.
