Ben Kuchera (Polygon) pretty much nailed it on the head. #Halo
always felt like it was about community - split screen, co-op, LAN party, multiplayer - doesn't matter, the game brought people together like i had never seen before (except from something like Smash or Mario Kart - hell, I bonded with my 10 year older brother over co-op NES Mario Bros) from roommates bonding , family members playing together, even kids hanging out at teen centers, etc - taking that function away felt like a huge part of the soul to the franchise got ignored. This article (different from the embedded image below) has a very dramatic title, but i felt it hit what bothered me pretty well. - http://www.forbes.com/sites/insertcoin/2015/09/21/the-new-loneliness-of-video-games/
chose to focus on revenue over community. Beautiful game and attention to details, a great step in the right direction - with two painful steps back.
