Wargroove, a game heavily inspired by Advance Wars, is coming to Nintendo Switch on February 1.

Finn “Tiy” Brice, CEO of Chucklefish Games, recently sat down with Siliconera to talk more about the game. When asked about their biggest challenge with Wargroove, Brice said the trickiest thing was working with a “well established” formula.

At the end of the day, they managed to overcome the obstacle by making “meaningful and interesting changes”. Here’s what Brice said in his very own words:

I think the trickiest thing was working with such a well established and perfected formula. It’s no secret that Wargroove is inspired by Advance Wars, Fire Emblem, Final Fantasy Tactics, etc. Those games are so refined at this point that deviating from the formula is scary!

I think, in the end, we made some really meaningful and interesting changes that weren’t simply changes for changes sake. I think that’s both one of the most difficult parts of the design process and the part we’re most proud of.
