Interesting, this topic really, I'm an f2p in kamihime but I once whaled in exvius, brave frontier, and potk. We also had similar discussion about how much does our whale actually spend on gacha. The most we found in our group spent a total of 50k$ before said person quit (BF), we know he's wealthy but his parents barred him from credit card when he got found out. I myself spent 2500$ on each game, but seeing the discussion here makes me pretty much a dophin lol.

I have question, does nutaku bought full license or partial license from dmm? the later doesn't include back-end access meaning they can't do anything about the rate, and the licensor tend to lower the rate when the revenue goes down (happened to potk). so which one is it?
