>>53192219>Battle Frontier vs. Battle MaisonSeven challenges with a variety of interesting gimmicks vs. five challenges that aren't that different. Point Emerald.
>Steven vs. rivalEquivalent - but Emerald also has Wally (the real rival), so that's a point for Emerald for having more.
>Safari Zone vs. Friend SafariActual area to explore that doesn't require multiplayer and has more than 3 Pokemon at a time vs. quick place to get 3 Pokemon from your friends. Point Emerald.
>Caves (and Lati@s) vs. CavesTwo caves (featureless) and a roaming Pokemon vs. Three caves (featureless - Terminus's non-Zygarde content isn't post-game) and a roaming Pokemon. Point XY.
>Gym leader rematches vs. Battle ChateauEmerald has four post-game teams per leader, Chateau has one post-game team but also some for the E4 (it also has other stuff but you don't need to be post-game for it, like Terminus Cave). Point Emerald.
>Mega Stone hunt vs... literally nothingPoint Emerald for not putting its establishing gimmick primarily in the post-game, in a one-hour time window. Seriously. This is nothing to brag about.
>Sushi High Roller vs. Trainer HillA five fight gauntlet vs. eight fight gauntlet. Point Emerald.
>Looker sidequest you didn't mention vs. nothing.To show I'm not a hater (I love everything in the first two decades of Pokemon, shame a meteor hit them right as they were gearing up to do another Kanto remake, that could have been fun), point XY since Emerald has nothing like this. Why didn't you mention it if you love the games so much?
That's 6-2, Emerald wins in a landslide.
