I enjoy "Heroes Call". Sorta action RPG in the same vain as "Balders Gate" or "Diablo". It is free as well with some in game purchase that can be made. There is a manditory wait time before you can continue with the story which is a bit strange.... unless you pay! With that being said you can replay past missions to kill the time for more loot. I have played now for a week or so, my guy is up to level 9 and I have not spent one red cent on the game so can't complain at all.
