Best turn based tactics game with great UI, "perfect information," RNG is minimal. The learning curve is only steep in the beginning but once you get hooked you won't stop until you have every squad. The gameplay is so satisfying because it's about positional strategy, rather than grinding (like fire emblem)
Compared to other tactics games: This is superior to xcom (because Xcom is full of RNG). It is better than fire emblem (because modern fire emblem is just waifus, not like the used to be). It is better than wargroove. The only tactics games I'd ever rate a 10/10 are GBA Advance Wars 1-2 and Into the Breach.
