Shayuri:
Sounds interesting. I can see a possible scenario - having sterilized your own world, you eventually discovered a means of planar travel only to be confronted with the shear scale of the planes. With your current configuration, you calculated that life could recolonize areas faster than you could sterilize them, and that's not even taking into account the possibility of resistance.
I need to dig up my variant 'ageless' aging rules I made for characters who don't suffer aging penalties. Basically, it replaces the aging stat bonuses with extra skill points, so it's possible to play something truly ancient without having imbalanced stats.
Nac:
Fractional bonuses look ok for me.
As for the bonuses, I'm probably going to make them all just +1 in place of +2, but they are treated just like level increase stats, so they would work with shapeshifting just like normal, base stats.
OnlytheStrong:
Pure fighter. I like pure fighters.
As for Ogre... I'll allow it.
And don't worry about the LA; just the Racial HD. With the racial bonuses I'll be using, the trade off is that something like an Ogre will get weaker/less bonuses than a 'normal' race.
