You already know my thoughts on this subject. I'm a huge advocate for more content, especially the kind that gives me something to explore. Exploration, all on its own can get me to keep playing a game. I was very tempted to stop playing Fallout 4 once I finished the story, but I thought I'd spend half an hour exploring. Needless to say I'd wound up putting in much more than half an hour, doing nothing but casually exploring and taking in all the things that I was finding for the first time.
Discovery really gets you with this feeling for the first few days or even year of playing. There's so much, but at the same time, so little to actually explore. Awe and wonder is traded for streamlined metas. Content is put under the axe to make the community feel more alive, but all it does is give people less scope to explore and ultimately less motivation to play. The number of systems isn't a counter argument, the quality of these systems is what should matter to people in support and opposition of this thread.
I'd personally love to see more, to be able to explore the rest of the universe that obscure vanilla lore hints at. Literally anything that I can look at for the first time, with fresh eyes and just say "Wow."
I'd love if we could stop pointing a gun at creativity's head, and I'd also love if we stopped having "intentions" behind the universe that's being built and simulated around us in game. I hope, as I always have, that I'll be made anxious by the mere prospect of wandering around to find something I'd never seen or heard of before.
