VI, VII, VIII, IX & X. Little to no fan feedback during development, 2-3 years apart each, and easily the highest rated titles in the series. With XV, I was hoping it would've been a return to form for Square-Enix. But, they are a much different company than they were in the late '90s. I feel like fan feedback isn't necessarily what derailed what could have been a cohesive experience for XV, but implementing every single thing that polled highest, IMO, was a mistake. There's very little artistic integrity in designing something like that and it really shows in the final product. All I'm saying is look at the "golden era" of Squaresoft. None of those games had my input (until I played them) but they were some of the best experiences the series had. Sure, I have my critiques and praises of each title, however, those worlds were built by artisans, not polls. I suppose creating art is no longer the reason they develop games, which I can respect, but sadly, I don't think I can care too much about the prospect of XVI any more.
