Best game

This is probaly best long term game i have ever played

The Grind is Real!! I love this game!

I have played this game for 4+ years. I love this game.I am level 30, I am powerful, I have a good alliance, and I am successful, and I have not payed a cent to this game. Give this game a chance and grind.

Definitely Pay to Play

We have created a family on our server & in our alliance and that makes it enjoyable, but having & spending money is very encouraged on this game. Especially to get to higher levels.

New Update: I quit this game, best game move ever! Customer support is heartless and does not care.

Update: I become more happy the longer I am away from this game that has the worst customer service.

A game that could be epic but the creators of the game are out of touch and have terrible customer support.

Update: Never resolved the issues. So, I quit , so guess what I am saying: “Game makers can F off,”

Rich tyrants and AI ruin the game

This game could be so much better if the developers actually listened with their ears instead of their wallets. I understand the game is here to make money for them but long term the player base quality is going to dilute due to the ability to annihilate every other player with PTW mechanics. Top spenders too often become the absolute tyrants of the servers they reside in, forcing other players out of not just any chance of Eden but many just leave the game. Their behaviour is completely ignored by reporting and the developers, even with screenshots of abusive chat due to the fact these awful humans line their pockets. It’s easy to turn a blind eye when there’s a lot of money involved. The reporting system is absolutely abysmal. Often they go without even being replied to be an actual human when you’re reporting serious issues.
TLDR: unless you’ve got loads of money to waste, don’t bother playing as the players who do will make you miserable and the devs do nothing about it.
