>>33100776From what I gather the trinity means new, innovative, and impactful conventions that will follow into newer pokemon games. As much as people like HGSS nothing it did was brought up in another pokemon game. Compare that to Emerald, which set the trend for post-game challenges of multiple battle strategies, i.e. the Maison still borrows from Emerald in the fact that there are multiple battle styles to participate in (just not as creative). Actually now that I think about it I might have to rethink that first sentence. Perhaps it's all that + the better version of the generation? Yeah, that makes more sense. So the 3rd gen introduced stuff like berries, natures, abilities, etc., and the better version is Emerald. Gen 5 gave us hidden abilities and streamlined breeding mechanics, and BW2 are the better versions. That would also make sense as to why Pt is often conflicted against HGSS, as they take place in the same generation and are distinct enough to not have a clear "winner" like with how Emerald is a superior RS and borrows from FRLG. And gen 6 didn't have a third game, so nobody ever considers that one in the trinity. So that's it, right? Trinity requirements are:
>introduced in a generation with innovative featuresand
>improvement upon those features with a game at the end of a generationThis also explains (partially) why XY was so well-received and would "obviously have a third game". A new type and megas are the epitomes of new mechanics and people were itching to see these new things refined. And Crystal doesn't make it because even though it's a third game it didn't improve upon what was already given, just altered the story a bit.
