Any heard of or playing this?
Path of Exile
Though I never played Diablo 3, it does remind me of Diablo 2 which I played over 10 years ago. There are some aspects of the game including the perspective is reminiscent of D2. You choose between 6 classes: marauder, ranger, witch, duelist, shadow, & templar. Here's where it diverges from D2 though, as you level, you get 1 passive skill point to invest in. The passive skill point map may look confusing at first but the possibilities to create a unique skill set are endless. Skills come in the form gems which you socket into equipment in order to use its ability.
Path of Exile is currently in beta. I've been playing it lately. The game is free and will have "ethical microtransactions." There is no gold in the game. Trading with vendors & as well as other players is based on scrolls, orbs, loot, etc.
