I followed it a bit but there did seem to be a lot of negative reviews, mainly performance issues IIRC.
- It's 4x RPG, but not with the usual territorial expansion as your focus is on the mage and his minions, not kings and castles- One main base, but yo can have "outposts"- Closer to FG2, though without the upgrading "tree"- The end-game goal is the same, but there are many many paths to it.
