D20 Apocalypse

I posted a post apocalyptic game with the image of Fallout. The group is free to already know each other since everyone is 4th level and use your combined 'wealth' to create your safe haven. Wealth isn't the same as money, but based on goods one can barter with. The story is about exploring for new knowledge while also surviving and defending the group against Mutant lords, biker gangs, Radiation Rogue Teams, Scavengers, and Corrupt oligarchs.

Players have the ability to gain knowledge for small space craft, futuristic weapons, and engineering technology to improve daily living. If there are any questions or discussions feel free to ask.

Is d20 apocalypse the system?

Yes, but a lot of the basic stuff for character creation is in D20 Modern. So players will need access to Modern, Apocalypse, and Future some also offers new skills, feats, and equipment.

I'm pretty sure I have that system tucked away. Is the game just about survival or is there a larger overall goal?

I've been pondering a character for this game. He would be a Tough Hero with skills in mechanical and structural welding. Don't know if you would allow this but I would like him to have participated in his spare time in eco challenge racing like the one in Fiji or the Hurt 100. What do you think?

I found a copy of the d20 Modern SRD but couldn't find anything in there about spending points on ability scores like D&D has. Since D&D 3.5 and 5.0 differ somewhat, especially at the higher scores (14 and above), I'm not sure which to use. Or if there is a completely different chart to use.

I may not have ever fully said it, but I am definitely interested in this one.
