Would have been 5 stars..

First I made an account it all went well after a day I tried to log on and then it says “oh you can’t make an account again” but obviously I made an account yesterday then it just removes the account removes the name, password. Also I actually spent 100£ pounds on this game and I literally can’t find a way to fix this.

Great Game!

This is a fantastic game and very addicting! It’s very fun because of the quests, story and long story short, everything is amazing. I understand why there can’t be an Offline Mode, because the data is stored online, but who cares the game is amazing! A feature I would like to see is the Crafting Book. Inside the book would tell you all the items’ recipes organised from most complex to most difficult. It could have the option to search for a recipe and help you when you can’t find recipes. I could be a perk that you have to unlock or not and it would be very helpful! Besides, it would be fine without it and is still very good! This problem might be my device, but every time I disconnect to from the server due to when I shut down my device, but every time it tap on the screen, it crashes this honestly is not that bad of an issue but if this is an issue with the game, please try and fix it in the future.

I love this game, as well as playing it daily, I try to stay up crazy late at night sorting out my realm or waiting for crops to grow in my farm! Any bad reviews are wrong. The creators of this game are the ones who pick the prices. Their game. Their prices. Yes, they may be a bit overpriced but so what! You can level up and earn things yourself and play with your friends, give them help if they’re new, give permissions to build to other people. Scamming can happen, and that’s a bad but good thing, as it shows that the world isn’t much worse, and the developers do their best to stop it all. The report section works fine. Don’t complain you don’t get any help, as the staff have hundreds of reports a day, and will get to you in time 😊.
