Taking a break from TSW but started playing Final Fantasy Brave: Exvius on mobile. Turn-base rpg, F2P, lots of fun. Play to gain character levels, player rank, gear, NRG (Expend NRG to play missions), gil (Money), and lapis (Used to buy extra characters). There's updates every couple of weeks with more characters, events and sometimes content (New island/zone to explore was added last week).
Linear storyline, can backtrack and do old missions pick up missed items or to grind a few levels. Some characters are new but most are from previous FF games. For example, I'm using Lightning (FF13), Cecil (FF4), Lenna (FF5), Tellah (FF4) and Chizuru (FFBE).
It's worth checking out if you're a fan of FF.
