★☆☆☆☆

Fun game at first. The problem is that the game stays off with ads for bonuses (when you want them). Once I got to around level 20, the ads increased and became involuntary - happening when you do some mundane action like collecting from the caravan. Could be a 4 or 5 star game if they kept ads optional.

Easy to play, helpful community and has the retro text based rpg with the added bonus of simple graphics. My only request is that we be able to choose our characters image at the start for free, the current price is too much, Id like to pick a character image that best fits my personality, but that's a minor thing, otherwise it's a phenomenal game!

Very simple and great UI. Easy to just pick up and play. Sadly the prices are crazy. $19 for the simple starter pack? That's insane for what this game is. And the "premium" is a monthly payment of $3.50. That's not crazy expensive, but why a subscription? I'm never against spending some money on a free game I enjoy, but this one isn't for me.

★★★☆☆

Nice game, simple looks and decent mechanics, but that is about all there is to it. There are a few visual bugs, and some things aren't explained and lead to problems. Also, pvp has a long wait timer, a third of an hour long. Buildings take most of a day to generate enough resources to upgrade one thing. You can't battle the wilderness while caravanning without paying for something. Oh, caravans, they make only a very small bit of money per hour, and can only be used for ten in a row, at a time.
