This is a good one. I can see where both of you are coming from. Madden really does split into some pretty different lanes depending on where you spend your time, and EA’s own mode breakdown separates things like Online Head-to-Head, Franchise, and Ultimate Team for a reason (lol, the corporate in me answer), so it makes sense that Regs and MUT can feel like two different games even when they share the same core football base.
On the playbook side, I can also see your point that more tools and customization appeal to many Fans, while the competitive concern usually comes down to how those tools are used rather than the idea of customization itself. Madden’s official playbook tips and gameplay pages already lean pretty heavily into scheme, counters, and adjustments as part of high-level play, so I think you’re landing in a pretty fair middle spot by recognizing both the creativity side and the competitive side without really dismissing either one.
