Destiny: The Taken King is having a refer-a-friend program. Sadly, it doesn't result in any sort of game discount, but has some in-game perks.
I feel like after the disaster of AC:Unity, Ubisoft really changed their QA process in terms of what is considered "ready" for release.
Well, if nothing else, we can't knock Bungie for beating around the bush...

The rumor is that Destiny 2 will change a LOT from the original, including adding PC support.

Not sure how I feel about Destiny 2. I played Destiny quite a bit, but mostly the solo campaign and patrols (Im not much for multiplayer, just bc I don't have the time to dedicate to get good at it anymore), but I did enjoy the missions, so Im sure Ill end up getting D2. I do wish that my current character and items would transfer over though.
