Have you ever heard of a "good" Lizard race in any other story or game? There you go.
Plenty of noble dragon-humanoids but that's dragons, not lizards...
Ehhh Chronotrigger, but that's amphibian and only one person turned into frog through magic, not a race...
Soul Caliber series takes the lizard people as just mindless neutral faction I think...
Star trek features gem'hadar who has scales and are very loyal warriors... well everyone in star trek is just about the same as another so I guess that's a moot point.
Star wars, same as star trek with its dealing of sentient lifeforms.
Last third of Godzilla films featured him/her/it as defender of Earth.

That's it! Now I'll play as space faring, loyal warriors addicted on drugs who are tall as moutains and breathes fire, defending Tamriel against alien threat!!!!!!!! Then proceed to do whatever the hell I want in mindless fashion.
