Destiny. One gamer asked about "open world RPG players who mainly like to play solo." Bungie responded that while it was certainly an available option, it would be "less fun".
According to the developer, "The company you keep, the challenges you tackle, the war you wage will all be products of the choices you make. If you never want to have a cooperative or competitive experience in Destiny, and if you want to experience every cinematic in private, you’ll have the option. We believe you’ll be having way less fun, and we think you may find it really difficult to resist the pull of our cooperative vortex, but when we say we’re building activities for every mood, that includes players who don’t want to party up."
Bungie also responded to a question about leveling. One users noted the weapon upgrades, but wondered about player leveling.
"The more you play Destiny, the more options you’ll have," responded Bungie cryptically, "Your weapons will evolve. Your gear will evolve. “Become Legend” isn’t just marketing spiel."
Destiny is due to be released for Xbox 360, Xbox One, PlayStation 3 and PlayStation 4. Bungie continues to dance around the possibility of a PC version, though leaked materials have indicated it was in development.
