If they didn't have to limit the engine to the confines of 8 year-old consoles, how much bigger/spectacular do you think Destiny could have been. I'm not talking graphics-wise necessarily, as a primarily PC gamer I think it looks amazing on the PS4, but I feel there were definitely places they couldn't achieve due to basically being limited to last-gen console specs.

While you have a valid point, I'd be SOL if they didn't. I'm not about to drop $500 on a new console (yet), so I'm extremely grateful that they support last-gen.
