I think the issue here isn't one of games like DQVIII and DQIX not driving engagement, both certainly did. They reviewed great, sold well and got lots of attention and positive response from western audiences. The issue is more of what happens in the 6 years between each of these mainline Dragon Quests and how SE completely squanders opportunity and loses any momentum.Exactly. MH4U was the culmination of something that came before.
DQXI isn't unique or accomplishing something different, if anything it appears to have had an arguably softer start. But even if it turns around and starts gaining some real traction it won't matter if SE gives it the same follow through they did the last two times. That's the real western problem for DQ and how it's totally unlike MH.
