Wildcard berths that can't beat teams without a winning record should have homefield advantage
It's simply about the console that more of your friends have for many people. The 360 having better multiplats (visually) definitely helped it but what helped it more in terms of being the go to system for multiplats was its one year head start, it's $200 cheaper price than the PS3, and Xbox Live.
PS2 was the weakest system out of the three for its gen but it got the majority of game sales mainly due to it still being a huge improvement over the PS1, its head start over the competition, and its ability to play DVDs. Millions still bought PS2s years after the Xbox and GameCube released (systems with better versions of multiplats) due to the PS2 simply being the more popular system with it also having great game support. It's funny too because the multiplatform gap between the PS2 and original Xbox was the biggest out of any gen so far.
This is part of the reason why I feel that power isn't going to mean much in terms of Nintendo's next console. They are already too far behind when it comes to online play for most people to even consider wanting to buy a system from Nintnedo to play multiplats. I guess it could be considered the wrong attitude to have by some but I honestly feel that this is the reason why Nintendo should make sure their next console is in the $150-250 range. Most are only going to view it as a "Nintnedo box" regardless of how powerful the system may be over the Xbox and Playstation.
I think we're at the point with the home console market, though, where an inferior console power-wise is automatically discredited by the vast, vast majority of consumers in said market. They can't take that route again. They need some of those consumers back--even as a secondary system alongside a PS4/5.
