NOW we're talking!
When I create my characters, I use the old MAYFAIR GAMES rules from the DC HEROES ROLE PLAYING GAME. 3rd Edition donchew know.
It was last seen being used for the BLOOD OF HEROES RPG.
Anyway, it works similar in terms of powers, however it's a points based system. Each character starts with 450 points, and you buy everything from your powers to your equiptment, wealth and what have you.
What helps here is, if you want to create more or less powerful characters, you halve or double (or quadruple, etc.) the base 450. This helps keep the characters balanced.
Plus, it has allowances for advantages or weaknesses for powers and/or equiptment.
Things like if it can be taken away in combat, does it need recharging, how strong is it, how much punishment can it take, etc.
It's all the little things that help get you fleshing out that character!
