True, but its still a very strange thing to introduce to a game if you dont want to make a complete "pay2win"-game.
Although Tibia was broken many years ago when PVP got broken and botting became a must in order to keep up with the rest, well, maybe its not so strange after all. Ppl buy ingame cash for RL cash so why not pots for RL cash, pretty much the same, although the money goes straight into CiPs pocket.
But its still a thing thats "over the line" to introduce, imo.
