That's the great thing, this game will allow people to play the game in many unique ways. There is no one way to play Destiny. While I personally will be in a group of about 3 I can see the fun in playing Solo. Finding other players randomly seems like it'd be all the more fun while playing Solo, it's much more significant. Imagine being in Solo, when suddenly 3 Cabal come out of nowhere, the fight is intense and fun but you are outnumbered and pinned down. Suddenly 3 other players come out of nowhere and together you take down the Cabal and continue through the Dungeon together and help each other find treasure and loot. You then go your separate ways and now have met some potential invaluable partners should you have more ambitious projects later. Meanwhile on the flip side, 3 guys are exploring a Temple and have a lack of resistance, they hear a commotion nearby and follow the noise. They enter a room and down below is this one guy holding his own against 3 Cabal. Obviously going Solo all this time has made this guy pretty tough and stealthy too. You decide to help him out and now have an additional supporter for the future. Who knows, one day you may need to build up an Army for an attack on the Citadel and that Tough Solo Hunter can be useful sneaking around and taking down the Generators. These experiences are what will make Destiny the greatest experience in gaming. Stories told will be endless. It'll be a true adventure.
