Akaneiro is a potentially cool Diablo clone ruined by a greedy free-to-play pay scheme. Yes, it's f2p- except on Steam, where you spend $10 on in-game currency to play it. $10 should buy you the whole game, and even then it's so simplistic it would be hard to recommend. And it still isn't feature complete, despite a $200,000 Kickstarter and charging microtransactions on an unfinished game. Totally unbalanced, too.
I'm not even sure what the state of the game is, either. It's still listed as "early access" but I don't even know that it's being worked on any more. From what I can tell Spicy Horse has moved on to other projects on Kickstarter, leaving Akaneiro a half-finished mess. Having loved their work on Alice: Madness Returns, I'm disappointed by this game and their questionable business ethics.
