What's your first impression of Eureka?

[Marluxia]

"17 months of development" comes from the fact that Eureka was announced at the 2016 October Fanfest.

Here is the Famitsu interview (from 2016, again) with Yoshi-P where he talks about Eureka.

So yes, they've had 17 months to get it right.

Included are certain gems such as:

Yoshida: It is the second expansion pack, and if we were to do the same thing all over again, a lot of people would get tired of it.

Yoshida: We did make adjustments to the Diadem after receiving feedback, but the thought process behind [Eureka and Diadem] is completely different.

Yoshida: Whatever the case is, it will be a content that doesn’t exist in FFXIV.
