Game length and replayability?

[Terrapin]

How long is the game and is it a linear play once and done or there skirmish mode etc? TIA.

Well, I've been playing the game almost 10 hours and I'm not even done with the second mission yet, if that tells you anything. I feel like overall the gameplay is fun, and I'd personally like to go through again after I beat it, on a harder difficulty, and try to do things better now that I know all the mechanics.

Length is an average of about 20-30 hours, depending on how much backtracking you'll do.

Replayability isn't really there yet. Unlike Darkest Dungeon/Xcom missions are storybound and fixed, and there isn't really much variety when it comes to your units and upgrades.

I am at the beginning of the 6th mission (I think there are 12 in total). I explore and collect everything, play carefully and slowly. 29 hours so far. No skirmishes, so it is your personal preference if you replay on harder difficulties.
