This game has no social features; messages strangers you see is possible in basically every online game, and organizing groups in forums isn't a game activity. The only way to be able to talk to anyone or access end-game content is to quit playing the game, get online, find several other people in forums (who are also not playing the game but, coincidentally, intend to soon), get back on your console of choice, add them to your friends list, invite them to a fireteam, and generally hope that you have enough people around to do whatever it is you want to do. This isn't a particularly difficult process, but this is a leisure activity to begin with, and minor hindrances will make a significant difference for enough players that a lot of people won't bother with it, and will opt to play a different game or just ignore a lot of content this game has to offer. This will lead to an initial slight decline in the playerbase as the laziest just ignore this minor hurdle and move on to other games, but the decline will accelerate as more and more people move on to other games, because it'll take more and more time (time where you're not even enjoying the game, since you're on forums) to organize groups to play with. This doesn't sound like a social experience. There's a good chance I'm wrong about nearly every prediction here, but with a ridiculous dearth of any social aspects to this game combined with the social requirements&benefits, I can't say that I'm optimistic about this game's shelf life.
