I really wish we had got online multiplayer for contests in ORAS, it would have been interesting to see a sort of contest meta exist, theoretically it is still possible for a contest meta to exist if a good way to play it in online multiplayer was found and enough people were interested. Also, I really would like a full side game focussed on Pokémon Contests, where it's made as in-depth as Pokémon Battles are. Pokémon Contests are such a great idea, feeling like a true proper alternative concept to Pokémon Battles both in-universe and in-gameplay, it just needs its potential expanded on. It feels too good of an idea to merely stay as some side thing in simplified form with only local multiplayer at best.
