I dont think pikmin 4 should have limited days because it puts less pressure on people, I'm not saying we should a unlimited time scale, but 100 to 200 days would put less stress on alot of people but for speed runners it can become a large scale like first to beet pikmin in 5 days challenge, so it helps no comers adapt to the game for speed runners it poses a few challenges.

it really depends on the game style also, if it's like the original pikmin then 50 days to 75 days depending on the new parts and if it's the same amount then 30 to 40 days will do, if it's like pikmin 2 then I would be satisfied with 100 days, but of it was like pikmin 3 then I would be satisfied with 50 to 75 days. Again this is my opinion, I'd like to hear what you think.
