The most fun is the online franchise mode with 32 players.
I am Japanese and have been playing Madden for nearly 20 years.
I made my online debut in Madden 20 and have experienced both H2H and MUT.
However, in MUT, inflation started accelerating around November, making it boring due to a lack of strategy, and in H2H, using certain play tactics drastically increases your win rate, which also makes it boring.
So we recruited some Japanese volunteers and held an online franchise mode with 24 to 32 people, and we were able to enjoy playing very much by analyzing each other's playing habits.
I want a system that makes it easier to recruit people to join the online franchise mode. Something like the official Discord, for example.
Personally, as a Japanese person, I would like a game feature that lets me find other Japanese players, but setting that aside, I want an in-game tool to find people who are interested in the online franchise mode.
