Hmm. I'm in on the d20 mechanic but definitely not interested in straight 3.5, its the exact opposite of rules lite. I'm running a regular 3.5 game right now and I really don't like it at all. I'd be willing to use one of the Microlite 20 rulesets though. They keep the basic mechanics but strip out the skills, feats, and all the fiddly stuff that makes 3.5 so slow and clunky. I've tried it a few times and its pretty good.
