It's not like they have infinite budget for everything. And I don't like the idea that when a big publisher publish a bad game, it's always the publisher's fault. Tri-Ace, Platinum and too many devs get more free pass than they deserve, while big publishers always get the blame.
Yes DQMJ3 is not very good, but they released DQB amd DQH2, both are great games. It's not like they are just killing off franchises and not doing anything else. This is how the industry works. You have hits and misses, and the end result shows that SE have more hits than misses, hence they are making money.
While i agree that the devs is also on the fault here, i don't think some of the game i listed there is the problem of the devs here. Especially on Bravely Second. The developer actually mentioned their small budget even after all their success in the west which is just idiot move by SE.
DQMJ3 series had always been a guaranteed million seller. Thanks to the bad word of mouth from many of the fans due to palette swap monsters, the sales fall down badly. Budget may be finite, but u sure should know where to dedicate here rather than goes cheap and end up killing the brand u had been cultivating for soo long.
And also, i don't agree that DQB is doing absolutely well there. As they failed to reach that Minecraft market which is the main purpose of this Builders game.
