I'm ok with it, to be honest I think that some of the Tales games were more kind of casual oriented in the first place, such as Tales of Hearts (which was a gem but felt a bit kind of more catered to a casual audience to me) and Tales of Graces (which makes sense because it was for the Wii)
There are so many Tales games and they all have things that I like and I don't compare them basically, I don't have a smartphone but I also didn't get a Wii until backwards compatability with the Wii U, otherwise I would not have played Graces at all...
So I may skip this one also, but I'm 100% behind the Tales series regardless and I think an era of tales which is more casual friendly could be just fine.
