This is a great game - at least, it would be. Rather than outright telling you that certain sections are inaccessible (i.e., pretty much the entirety of the game), you are forced to find this out on your own. The full game is around $24 to buy all of the expansions, $5 per area, but you don't figure that out until you've already invested a significant amount of time into the game, got to those areas, and found that they were blocked off.
This would be an amazing game if it were fully free, mostly free (with some paid sections), or even fully paid-for, but no. It instead pulls some weird bait and switch.
Again, almost ALL of the game is inaccessible, past the first villiage and a few small areas you can explore. It should be listed on here as an unpaid demo instead of a game, but instead they went the deceptive route. In short, don't play this game thinking it's a free game; it's not.
