I want to get both and I want to know if it's worth it.
It is only worth buying both if you have two consoles that can support the games so that you can get 100% in each game, even then it's not really worth it because of how much money you spend and how much fun you get out of it. Honestly just buy one version, it's still really fun and you can always use a friend's counter version.
You can if you want. You can benefit from that because you would have all the Pokemon from both games at your fingertips.
It is definitely worth it dude. It is probably the best Pokemon game yet.
