Looking for Advice on Race Design

[DirectorTsaarx]

One thing to note about playing with the happiness figure: if you're using a Temporal race, you get the "Temporal Vacation Facility" (TVF), which gives the best happiness bonuses (+2%, +4%, and +6% for the various levels). So you might be able to get away with lowering happiness. The first facility I build in any new system is that TVF (and don't forget to build one on your homeworlds (or at least in your homeworld systems) as soon as possible).
