With open world rpgs like Skyrim, Fallout, etc. Jrpgs just can't complete. They'll sell well in Japan but outside of Japan they don't anymore. The lineal paths and lack of choices have hurt jrpgs
Thats just not true.Nier Automata, Nioh, Dark Souls and many more had and has excellent sales in the west, and they are all JRPGs.Now, if you mean turn based RPGs, there are FE, Pokemon, Persona, DQ(of which I have a very good feeling that XI will do very well on the west) Bravely Default and many other smaller and bigger franchises finds succeesses in the west.You dont need to sell millions upon millions to be considered a succeess.
