I'll be honest, the biggest reason this game was on my radar was because it was being published by two of my favorite farming sim game developers, Marvelous and XSeed Games, developers of the Story of Seasons (Formerly Harvest Moon) games! I never played a "fashion designer" game before, and frankly, I never had any desire to play them, this game changed my views and made me realize my love for fashion design.
This review comes after playing the game for about 15-20 hours so far...
The game is basic, plot wise, but the longevity lies in the online multiplayer (no NSO subscription required, so bonus points there). I hit the credits after only one day of playing. I continue to play because I come back to see a new trend going through the game world, and I get inspired to make new outfits for players and NPC'S alike.
Long story short, if you have any amount of fashion sense and love for creating outfits for people, and you don't mind a slow burn after the credits roll, I can't recommend this game enough!
If you're on the fence about it, I'd suggest waiting for a sale.
