Really this applies to any level based RPG, so whatever level range it has (ie, 1 to 30, whatever is the top level).
I was reading a post of a play account and it struck me how the very short term here and now appears to be a game in its entirety. And heck, I'm talking a possitive play account here, not someone who hated a game from playing only one session of it, but is talking about liking it.
What'd be interesting is like those iron chef or 24 hour game design things people run, have something like a level 20 in 20 sessions (or less) thing, with any system that uses levels. A whole bunch of people just design each adventure to really push as much potential XP as possible while trying to still use the XP system without hacks. Like one of my previous posts, but amped up even more!!!1!one!
I think the accounts of play would be cool! Though it might spoil the 'we played for three years and only got to fifth level!' type play for people who previous dug that.
The main point is, instead of talking about the game using one single session as an example, you would talk about the game from an entire 1-20 stand point!
