Xbox boss Phil Spencer was a big fan of Destiny 1, having played some 700 hours of it. He's also logging time in the sequel, and now he's told us more about his time with the game. Speaking to GameSpot at the Brazil Game Show today, Spencer said he keeps his fireteam (and sometimes his Xbox Live party settings) open so anyone can join him. His gamertag, which he frequently shares openly on Twitter and elsewhere, is P3

He has to kick people out from time to time, however, because he's not a high enough level to play end-game activities like Leviathan raid. He told us at the show that his character is Power level 237. You need to be at least 260 to play the raid. Not being a high enough Power level for the raid keeps him awake at night, Spencer said, perhaps jokingly.
