The game starts off pretty good but becomes a terrible grind pretty quick. This is even coming from someone who paid for a month of the Dragon Pass. Character and base upgrades start off reasonably priced but quickly jump up to 14k+ gold. Rewards for winning is less than 50 gold. Same for achievement rewards. It's a shame because it really is a fun game but there's no light at the end of the tunnel. It will take me weeks to do 1 14k upgrade on 1 character, let alone all the other characters.
