My favorite systems do not translate well to this environment. I love the element of chance in a game, so random creation is awesome for me, in tabletop it doesn't matter if someone rolls like a god and someone else rolls more average because everyone is participating and creating fun together.
Online it's a whole different ballgame, if things aren't as 'balanced' as they can be then people will whine, bitch, and moan. So we go with systems where everyone starts out with the same points. It's still not equal because one person's build might be better optimized than anothers, but at least the potential for equality is there. Everyone had the same points to work with at creation.
I still am tempted to use the old FASERIP marvel system for a game though, with random creation and everything and just say Fuck Balance but everytime I try I see the damage an Alien, Deity, Angel/Demon could do if the dice decided to love them with 14 powers and the like while another pc might roll up a normal human with two powers, and roll that they can glow and smell the past.
