Well, to be fair, they have been making Pokemon games for 20-odd years. If the franchise wasn't such a big cashcow for Nintendo, I'm sure we'd see Gamefreak working on a lot of different, new IPs. But as such, that isn't the case. *shrug* I do know that if they delayed SwordShield just to add in a Nat'l Dex, there'd be a massive uproar from a lot of Pokemon fans.
well given that fans demanded the national dex, they might be willing to wait. but another option could be making updates. Release the game, then little by little, add Pokemon.
Its kind of like with Pokemon GO. At first it was the first generation, then little by little, they added the other, along with new additions like battle and trading. We're closing in on Unova so I'm excited xD all that's left is Kalos and Alola. Then Galar once its out.
btw did you see the trailers? Now they have Galar region Pokemon like Weezing and Zigzagoon. Also, that new evolution of Linoone's reminds me of Gene Simmons from KISS xD
ugh, I'm old lol they're not from my generation but I know who KISS is
