Bungie has been talking a lot about Destiny's systems, but there hasn't been a great deal of discussion about the long-term game. What's going to keep players going in the long term? According to a recent interview with the designers, it's raiding. They'll be focused six-person runs that are meant to take a long chunk of time to accomplish, with no matchmaking services to fall back upon -- players will need to clear time, sit down, and get ready to really chew through challenging content.
Not into that sort of play? There's also a set of bounties available on a daily basis, aimed at rewarding players for what they're already doing and creating a parallel progression path along that line. There are also daily challenges and Nightfall activities to keep players going. If you're looking forward to the game and want a closer look at what you can get from endgame, hop on over to the full preview.
