I think GF rewrites the engine from scratch everytime because seriously this makes no fucking sense. Specially since you consider the fact that if you name your rival "You", the game thinks you are using the in battle item when fighting against him, bug that didn't exist before.
You have the concept set in stone, it's a fucking remake, the second one at that. You don't have to brainstorm anything.
You have pokémon models and animations done, on top of that you'll only use 151 of them, so whatever polishing there needs to be there's less work anyway.
The music? The music is the same but remastered, you don't have to compose new music from scratch.
The dialogues? Almost the same too.
The AI? Dude, have you seen how your "rival" walks like a robot? The pathfinding is atrocious, even a single dev can make better shit within a week (t. dev)
The battle system? It's the same as ever with a few tweaks.
I'd say out of those 100, 70 of the people in the "team" worked to market this game, that's including the monkeys behind their social media accounts and the actors in the trailers.
