I absolutely love this game, it's a squad based action/stealth game that controls like an RTS, not only there are very few games like that, but this one differentiates itself even further by having swordplay, basic base management and the choice between lethal and nonlethal approaches. As an example, a basic mechanic is that if you try to avoid killing enemies during story missions then more merry men will join your band in Sherwood, which you can then send on missions. It's like a budget medieval Outer Haven.
However, be warned that the Steam version is virtually unplayable on a modern system. I hope you have a computer from 20 years ago or else you won't be able to play this title without experiencing slow downs and input delays, which is a real shame. There is also a mod which apparently fixes these issues for most people and it's easy to find a link for it on the Steam forums, but it didn't work for me.
The GOG version runs much better, but only the Steam one supports my native language, so I had to make my very own Frankenstein's monster in order to play the game like I wanted to.
Also, just to iterate on how little this publisher cares about Robin Hood, the background picture on the Steam library is from Desperados: Wanted Dead or Alive, a different game by the same developer. Shameless.
