This is an auto-battle game with high production quality. I bought 1 month package, so I'm not f2p.
Usually I play for 20 minutes in the morning and another 20 minutes before bed. It's a low commitment game which respect my free times.
I played this game on 3DS but I don't remember if I ever finished it. I loved the Rune Factory series so when it came to steam, I bought it for nostalgia. It's a relaxing and charming game, I started it up whenever I'm in the mood for planting turnips.
