So here's the deal. This is a PbP adaptation of a convention game I've run several times. The rules for that were
literally "bring your favorite character". What's the character you always wanted to play? I want to make that happen, including playing something from another system, or your favorite character based on literature. I've had characters from Star Wars d20, Champions, Rifts, White Wolf, D&D 1, 2, & 3, etc., and everyone had a great time.
If you really want some D&D 3.5 generation guidelines, here you go (though don't feel super bound by them):
- Experience -- 9th to 14th level
- Stats -- 50 point buy, alternate requests honored with justification
- Wealth -- Standard WBL, custom items, oddball requests honored with justification (like, say, if you are playing Gambit with a DoMT)
- Classes -- Any.
- Alignment -- Lawful Evil or equivalent. The only constraint is that your character must play well with others of a similar mindset (no intra-party conflict).
Yes, this is a high-powered game, and I realize that some people aren't really comfortable in that setting. However... you're going to need all the help you can get.
EDIT: I just wanted to say that the way to go about this is not to start with "what are the chargen guidelines", it's to start with "what's my favorite character", and we'll work to realize him/her/it. It's possible that it will be the character that no one else would let you play.
