Online gaming is over valued on message boards. It's important but is only the focus of console makers and game makers because they can extract more money from you by making things online based. There is a huge market for local co-op and think that is part of the reason Wii was so successful lots of people want to just play with their friends and family at home.
It really sucks local co-op died as fast as it did. I also think online multiplayer has kinda declined since parties and all of that. Took the fun out of trash talking and there really hasn't been a lot of captivating multiplayer games so far. Titanfall and TLOU are great starts, though.
