Allods Online's community isn't happy with the game's cash shop prices. Currently, the cost of increasing your bag slots from 18 to 24 is $20, which is considerably higher than pretty much every other free-to-play game on the market. It's not entirely clear whether this is some kind of back-end mistake on gPotato's part or an actual pricing change.
And looking at the general section of Allods Online's official forums reveals that, in fact, a lot of players are pretty upset over the whole fiasco. Some are proclaiming rage-quits while others are considering boycotts but nobody is happy about the news. Of course, some more level-headed community members are attempting to communicate with gPotato in order to get the prices changed to more reasonable prices -- something which is apparently true of the Russian version of the game. We'll keep you updated as the story progresses.
