This game is a cross between the classic rotk games that I loved growing up, and the card collecting games I have become addicted to these past few years, and while there is an ability to p2w, I have been playing a month, currently top 50 in arena (server) without spending any real $$$. The game is very generous with in game currency, including the main currency you would spend real $$$ on. Great game, already addicted (Guan Yu is OP)
