Custom games are very useful for planning strategies, gameplans, testing weapons and armor, and playing around with friends. If you have ever played the halo series, you'll know about custom games, and how useful they are. Custom games are private games that you can invite friends to, and mess around on. You can potentially make a custom game in Destiny by having you, and your friends search for a crucible game at the same time and hope to join them. But it will take many tries and will require good Internet connection. If custom games were implemented into Destiny, it would be awesome and would probably draw a lot of attention from players. But, that's just my opinion. If any gaurdians out there want custom games,feel free to message Bungie and join the forum. If you have any questions, just ask, and I'll do my best to answer them. -Tactical Man259
