It's alright, but not at full price. Much like a metroidvania but with worse level design, better variety of weaponry (spells) and a bright outdoors atmosphere
WARNING: If you're annoyed by games with sub-par graphics, look elsewhere. This game looks like it came out for Windows 95.
The immersion factor is 7/10, but there's a lot of text and need to grok a lot of concepts to play, but you get through that about an hour in. Technical problems prevent the game from being totally immersive. For instance, the game halts for half a second when the music track repeats.
The fun factor is 8/10. Leveling up your character's abilities and the settlement. Leveling up your settlers and sending them out on missions to collect resources for you (ala Assassin's Creed or FF Tactics) is a fun addition.
All in all, it's a game I could definitely spend hours and hours playing. There's real depth to this game (if you can get past the derpy graphics).
