Last mainline Dynasty Warriors came out in November, the next one's due in August. In that time period, so far we've had Arslan and Hyrule Warriors Legends, while Attack on Titan, Berserk and Dragon Quest Heroes 2 are likely before the year is out. They now how to turn those out.
That said, I'm all for these games when they have larger than life characters. One Piece Pirate Warriors was surprisingly fun, almost by virtue of its wacky art alone.
O.o What? Last main game I can find for Dynasty Warriors is 8 which came out in 2013. Last expansion version of 8 was Empires which came out Feb. 2015 in the U.S. I must be missing something here.
