Most everything in this game requires you to spend money. Most areas can only be unlocked with real cash. Many unique miscrits requires you to pay as well. Items (relics) also cost real money. Energy to heal yourself can be purchased. Pretty much another of those "whoever spends the most money wins" game, taken to a new level since you also need to pay for content. Yes, this game is a demo if you don't pay. Also, I am pretty confident that Kong admins on purpose inflate rating of those "multiplayer" games with real money shops to push them on the front page so they get a share of the sales before the money-sink... I mean before the game dies.
