While playing Mario Galaxy 2, I started thinking about how cool it was running around on the different planets, even though they're very simple and super small. It really had me wondering when R* will be able to create a seamless planet? I guess what I'm really wondering is, how large a globe would have to be to look flat from the player's perspective? Is this a realistic option for this console generation? Probably not, but I'm curious when technology will allow this, and what the main hurdles would be?
I would think one big issue in terms of playability would be making sure the game world isn't impossibly big, but definitely multiple times larger than anything every made, because it would still need to feel like you're on relatively flat ground. If somebody much smarter than me has any idea what the minimum size this hypothetical planet would have to be, I would love to hear your thoughts. I'm sure there are a few levels of math I didn't take that would assist me right now.
If R* built the game world as a planet, they would have endless possibilities for the environment, and story. The moon in the sky would actually be reachable if you break into R*'s version of NASA and steal and rocket.
I just see this as a logical step in the future of open "world" games. Any thoughts?
