It's always good (and mature) to come in and start a thread by saying "I don't give a shit what any of you all have to say, my opinion matters to me more than yours". If that were true, what's the point of even starting a thread then? If you already know your opinion, and claim not to care at all about anyone else's, then why even tell anyone your opinion? In hopes that people will pour in (after your already confrontational intro), and agree with what you have to say? Buy why would you care whether they agree with you or not, when you've already clearly stated that everyone else's opinion means little to you.
It's an odd modern internet dichotomy we seem to have, of people wanting their opinions to be heard, but not giving a damn about hearing the opinions of anyone else. They want their own views to be validated and recognized by others, but don't care about recognizing, much less respecting, anyone else's views. Just another extension of the overall "everyone wants to be heard, but nobody wants to listen" syndrome.
Regardless of the poor framing and lack of tact, no, honestly, the industry does NOT need more multiplayer online games. It needs more GOOD games, period. And far too many big franchises are already focused heavily on multiplayer, while being VERY light on single player content (not surprisingly, mostly shooters), such as CoD, Battlefield, Destiny, Titanfall, etc. etc.
That is NOT the direction the industry needs to head further in.
