On his blog, Brian Green ponders whether such a system can't be simplified in a way that would encourage a deeper understanding for players who don't take their games so seriously that they've got their gear progression mapped out in Excel. His first suggestion is to sweep away derived stats, or more accurately, JUST have derived stats, and ignore the base stats that influence them. Seems reasonable enough, if a bit more long-winded. His second suggestion is to take away the level curve, making stats behave the same regardless of the player level. It's an interesting idea in the abstract, but one wonders whether developers, and indeed the players they're developing these games for, are ready to put in such a radically different system.
