releasing singel player games in 2011. gaming is a social affair it is not the ps2 90's anymore. co-op online is where the fun is. every game should have an option to play it through with a friend.
I beg to differ. Games that have multiple player characters/allies should support multiplayer (as in
Secret of Mana, for example,) but shoehorning it into
every game is just going to ruin games that aren't designed for it.
As for me, I'll vote for the ur-trend:
everybody blindly copying what everybody else is doing without any regard to whether it fits in their game or was even good to begin with. That's how all the rest of these trends proliferate.
