IDK, I always had a very specific taste in games focused more on JRPGs, 3D mascot platformers, and puzzles. and those niches haven't exactly grown over the decade. So I never really got a chance to feel fatigued in the AAA nor indie spaces because that niche is more in. On the contrary, the platformers seemed to be nearly dead until Crash gave the genre a resurgence.

I'm not as excited for FF16 as I am 15 but that may simply be because of themes (I'm still buying day one tho). FF15 was this modern/steampunk feel mixed with high fantasy and I prefer that over the seemingly medieval/low fantasy feel. But the gap between those games were 7 years (or rather, 5 years if you count FF7R) so I wouldn't say I'm fatigued of big budget JRPGs... because there aren't that many.

Starfield... well, I'm just glad we're getting closer to Fallout 5 :). Never could get really into Elder Scrolls. I'll probably inevitably try out Starfield, but it's not a high priority.
