#1 is a very good point. From that angle I probably would start a new world myself at some point, though I'd probably always keep my "main" world, too.
For #2, in this particular game there's nothing that should cause you to do that. With other games -- Neverwinter Nights comes to mind -- I can definitely sympathize on this point, though. That's definitely where a lot of the replay value. In AVWW, it wraps all that right into the main game, though.
For #3, that's fair enough. Though in both Minecraft and AVWW you can just explore more and more to find those interesting vistas. They just might not be close to your original start or whatever. In Minecraft that can be a problem unless you use one of the third party servers to let you set a new start position, so you're not having to truck it back from world center every time you die. In AVWW, that will be part of the game itself to take care of making sure you don't spawn ten lightyears away from your current area of interest.
For #4, fair enough. I tend to devalue this one because time is so limited for me that I'd never finish a game if I restarted it every time this happened to me, so I just wind up exploring around lost for a bit when I come back. It took me six years to finish FFX, for instance, with multi-year gaps between some of my play sessions. That took... some adjusting to remember what was going on.
When I was a kid, I played every game many times, though, so I wouldn't have thought twice of it then. I must have started 30+ games of FF1, and logged 10+ hours on each of them, before ever beating the game. Not long after getting the upgrades to the improved classes from Bahamut, I'd lose interest and drift off to Zelda or something, and then I'd come back days or weeks or months later and decide I liked the earlier part of the game better, so I'd play it again with a different party. So the more I think about it, the more I can relate; I just don't think of AVWW as that sort of game.
For #5, definitely can't argue.
All good, and thanks for providing the details and clarity. In reality I don't really care how many worlds people create -- if you want to create a new world every week or every day, knock yourself out. Maybe for some strange reason, like me with FF1, you just like playing the first ten hours when everything is relatively low-level and the world seems broader and more tame. Maybe that's just so compelling you want to play that over and over again instead of getting things more built up, or even building things up and going off for a new adventure in some new wild area. That's cool with me.
But for those who want a sense of constancy, to have a really long-term amount of play without restarting and losing progress, you
can do it, and that's what is different and nifty here. In the most extreme of completionist circumstances, I might get 120 hours out of the largest Final Fantasy game. On the shorter end, some of the older ones are closer to 20 or even less. That's a long, long time in any stretch, and those are all great games that I love, but once you pass a certain point... that's it. Your involvement with the world ends, unless you want to relive the same experience again. It's the same with books and movies, of course. They are a finite experience.
In the case of AVWW, the goal is to make that not be so. That there's never a point where you
have to just be done, because everything is static now and nothing is new or interesting. We'll see how we do.
