At the time it was fun, because the sense of community due to the boom of re-emerging players as well as the PSS being so good made the online experience really fucking great. Pre-bank competitive was an incredibly fun meta, trading was super fucking easy, and breeding was more laid-backed and streamlined.
But other than that, the game didn't have much going for it, and it started so much of the garbage that we saw in Gen 7 and are now seeing emerging in Gen 8. It's also just forgettable, and honestly I can't really pin down why. It's probably nust a lack of actual, uniform indentity.
X/Y felt super incomplete, and I can only assume they were going to attempt to fix that with a 3rd version, but either chose or were forced into making a new gen for the 20th anniversary.
