Have you ever played Kingdom Hearts Union X? How about back when it was called Unchained X? This game just celebrated its fourth anniversary.

I've been a fairly active player since around launch, but with frequent breaks. I looked in my stats and I've just hit my 250th day played. Not in a row, just overall in the past four years. Since I've played for a long time, I've been around for "good deals" to spend my in game jewels on. As far as F2P games go, it's a lot of fun and it doesn't suck you into a gacha nightmare. I'm caught up with the story and haven't spent a dime of real money.

Where you'll have to pay is if you want to be competitive with the PVP. I'm not touching that. There's always someone with more free time and more money who will obliterate you.
