I reluctantly get pulled back into this debate...
It is valid to say" I do not like leveling" or even "I do not think that many people do not like leveling" but it is invalid to say "Players don't enjoy leveling"
I am a player, and I enjoy working hard to see not only improvement in my character, but improvement relative to others who do not bother to train. What you call "leveling".
I enjoy the process so much I have started at least 8 characters in PS, just to keep the process fresh and to compare relative rates of improvments among different techniques. I also have close to a dozen Characters in another game I play. To be clear I joined a guild in one so I could donate 95% of my expereince to the guild, to decrease how fast I level so I could better enjoy the process, and learn more about the game!
Am I a majority? No, I suspect not. But do I exist? yeah, I think I do. (gooOOOO Descartes!)
I believe Zanzibar does not enjoy leveling. I also believe he tends to try to speak with more authority than he possess. When you try to speak for everyone, you speak for me. Please do not do that.
thesoundless's statement... "I do not think many..." is fine. I disagree with it, but it is a valid assertion.
I also suspect that how levels are handled in PS is pretty much set, and thus this self flagellation is moot.
I think the debate topic is a good one, but I notice emotions tend to rule the day when it is applied to PS specificaly. I wonder if there is a forum somewhere on the internet where Devs are/have discussed this already. PM me if you know of one. I would like to link to it on one of my sites.
of course,
http://mu.ranter.net/theory/general.html has a lot of good ideas as a starting point for stuff like this.
