I get bored very quickly in Pokemon games nowadays, what keeps you going? Only ones I properly finished are Fire Red, Emerald and Black.

i finished them too. New pokemon games are boring but i like 3ds pokemon games

Many years ago I bought Pokemon Y, Pokemoon Moon, and Omega Ruby, and they're part of my backlog of games. If I was to play one, which one would you choose?

I recommend you to play pokemon omega ruby
