I voted Zelda, even though there are really only a handful of Zelda games I really love. To me the NES/SNES Zeldas are great and so are BotW and Hyrule Warriors. Everything else I've tried is kinda "meh". But I still call Zelda my favorite franchise, because the games I love, I really, really love.
After Zelda comes Advance Wars at #2 and then Mario at #3. Advance Wars has actually been their most consistent series for me. Days of Ruin wasn't as good as the others, but even that is still a solid game. The others are great. I wish they would bring back Advance Wars.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
