My love of the under-sea is well-documented on this website (and some other ones). I can’t help it, I’m at Atlantean at heart. I’d live under water if I could. I have lived under water for most of my life, for an extremely generous and disappointing interpretation of the idea. Every game that opens up by telling me most of the action will take place sub-H2O has an automatic head start; I’m a simple man to please.
And if a game tells me it intends to fill that setting with tactical turn-based combat, persistent customizable soldiers, and randomly-generated worlds full of uncertainty and mystery and danger? If other sites bill it as ‘XCOM meets FTL, but under water’? It would be hard to laser-target a design document more directly to my interests.
