Ok nice Idea but... How do you plan to make maps equally useful for all the 3 races, as all of them will need a different amount of resources for their ships and techs.
A starting point thats working fine for TEC will be alot worse for an advent player, as advent will need alot more crystal than TEC, as vice versa TEC will need more metal than advent.
So basically if you will answer "just have as much of anything" you will automatically favor Vasari, as those need less metal than TEC but more crystal, and the other way around with Advent.
The only way to be able to deal with this, would be to have a set starting layout for each race, which would need to placed according to the race chosen.
If you won't do that, it's as good as any map you can create in the forge.
