This is an amazing mod, I have to be honesty and say that I hated vanilla M&B:W but with this mod you have things like money, renown, balancing and troops overhauled. You'll make enough money to keep armies active, which was kinda a problem for me in the original having a massive army slaughtered early-game and then my character being screwed, it's easier to hire lots of troops and good ones too. Your character isn't underpowered, now he starts at level 10 with high skills in a selected type of combat so you don't get royally screwed every time you try to fight. I have four times the renown I would have gotten in the original, which is good because I never got far in the original because the grinding for renown.
No more grinding, just more of what you want to do
