Both The Chato'matou (Gormoshk don't care) and the Etty are stronger with more sunlight.
Differentiating between star colour and a planet slot (i.e. distance from star) is probably too complicated to be included and probably won't be. If it is, however, then we''l probably need to distinguish that too.
Although for any race that does not eat food, food becomes worthless. But any world with either the Primary or Secondary Focus Balanced will produce some food. Meaning Balanced Production is a waste for them (unless they get say -X to food and +X to whatever they eat... or if they just produce less for a focus ... instead of +5 and +15 they get +4 and +12.. and can't produce food)
Don't forget about trade and multi-racial empires. Just because a race doesn't eat doesn't mean they'll never need to farm. Although I can see farming simply being removed from their "balanced" settings, or making it optional.... at the risk of making things unbalanced and confusing....? Probably not.
Well Removing it from the Balanced Setting (rather than making it optional) with some bonus to the balanced setting would be the most reasonable. The "Optional" for trade/multiracial would be setting one of the Focuses to Food.
And Choosing Mineralvore, etc. would enough of a choice that you know that you don't need food [it would just be wierd that on first contact this race of non eaters has this Massive stockpile of food they aren't going to use].
Actually "Food requirements could be even more flexible
ie POP unit Requirements.. decreased requirements need increased race pick points
Food: 2-0 [default 1]
Minerals: 1-0 [default 0]
Industry: 1-0 [default 0]
possibly Count production as just Minerals plus Industry
So you could have a race that can only survive on their Homeworld with some food focus [assuming you were silly enough to do that] or you could design MOO2 Cybernetics.
