This is Island Kingdom Review

I thought it felt a bit like a Chinese game and I'd quit after a short while, but it's actually quite well-structured. The characters are pretty and collecting them is fun. You also get to interact with other users while cooperating on missions in the guild. Tip: Basically, if you're free-to-play, continuously collecting resources from your territory is key. Other than that, participate in events according to their schedule, increase your generals, and manage their promotions. Have fun playing~
