Thanks for the goblinoind info
While you are are the mark, Bront, I'd like to add a little more before the issue is closed. Per our experience in LEW, parties are rarely all the same level, and the idea that everyone needs to start out at the same power level isn't necessarily all that relevant. Having played in more than one persistant world, I'll add, having an inn where players are recruited tends to yeild more varied parties of different levels, while having a recruitment thread where DM select their paries from an OOC perspective yeilds more balanced parties. Not that one is better.
In any case, all PLAYERs should have the same opportunities, but not all characters, necessarily. Having different starting point buys gives players the opportunity to create a wider variety of characters. Power gamers will take advantage of any system, but I see this more as a opportunity for variety. Didn't you guys do something similar with Living Supers? That's where I got the idea. Perhaps having a lower spread would still be interesting. Say a 28 point buy, a 32, and a 35. Whatever, that's my 2 cents.
