I've played Halo and Destiny, both the first games (and Halo was back when it was released), and I remember a bunch of stuff from Halo but I can barely remember fuckall about Destiny. Destiny doesn't have any interesting art design to make anything memorable. It's like that Jim Sterling clip where he comments on a japanese Batman thingie that is just details upon details upon details. There's so much hyper-realism detail that nothing sticks in your memory.
The only thing I remember is that you have some little box drone thingie flying around with you. I don't remember any of the worlds you visit, any of the characters, any of the factions, any of the vehicles, any of the weapons. It's all just a blur.
I'd rather work on something memorable than something forgettable.
