Homebrew Doctor Who

[Kosmopolite]

Hello, all.

I'm fairly new to RPing, and even newer to GMing. I've started working on a campaign based in the Doctor Who universe (sans the Doctor for balance). I've been using the d20 system to design the campaign, convert monsters (gargoyles minus stone powers for Krillitanes, for example) etc. My trouble now is designing the player classes. I want to have a couple of races (humans, humans from the past, ill-cloned Sontaran, Cat people... Still working on this), but I don't know how to do it. If I used the race/class process of DnD 3.5 or Star Wars, then it won't be compatible with D20 Modern/Future, will it? And if I just use the Strong/Tough model, then the characters won't feel different enough. Y'know?

Any thoughts? General tips on homebrewing? Comments on how I've got it wrong from the start?

Thanks in advance.

Well, the Malmooth (http://www.giantitp.com/forums/showthread.php?t=87485) are a loosely-adapted version of Chantho's race from Utopia. I've also got some homebrew Daleks kicking around, if you want to give those a look.

That'd be good, thanks.

To avoid people assuming that this is turning into a two-man conversation, I'm still looking for tips on the player characters, etc. :)

As I mentioned in my other thread (http://www.giantitp.com/forums/showthread.php?t=87558), I'm also considering GURPs. Any thoughts on that?

Homebrew Doctor Who? Sounds good. Don't forget the Ice Warriors!

I think the trouble with player classes is that most of the classes are fairly consistent; it's more the races involved that become varied in a Dr. Who world. Most of the classes would probably be things like medic (UNIT, tesh, etc), soldier (UNIT, dalek, cyberman, sontaran, etc), barbarian (androgum, scotsman, sevateem), savant (gallifreyan, tesh, etc) - some races would be appropriate for some classes, as noted; others, like the Varga would probably be basic monsters, and some like Solonians would be tough to balance.

Seems like an awful lot of work that I would be far too lazy to get done. :)
