As someone who plays of these "gatcha games" than anyone really should (it's an addiction of mine), I think I'm going to pass on Mobius. I already have Brave Exvius keeping my attention, and I much prefer the look (and, judging from videos I've watched, feel) of that, when compared to Mobius. The game is a battery drain too (the graphics do come at a cost), and I'm already finding my battery time limited with the games I do play. :/
It's probably for the best really, as I'm not so sure I have enough time for another gatcha game. That being said, I'll probably give the new Naruto Shippuden Ultimate Ninja Blazing game a try...
