I'm fairly tech orientated in my games, but i do get a boost to production/research when:
go for planetary improvements fast - 10% production(military & social) an a 10% research
galactic warfare and the next red tech (can't remember what it is) for 10 % to military prod each.
Its then up to the situattion as to what to research, but these inittial bonuses help a lot.
do try to get to interstellar federation as soon as able though.
The colonisation rush:
the first two colony ships are rushed maybe the third if i hit one of those jackpot anomalies.
the rest get built until two turns are left, then rushed to save a fortune.
Its pot luck with the planets because of bonuses but as a general rule - go large unless you're feeling lucky.
build starports to get them scouts zipping about meeting people and planet hunting.
The home planet:
rush a factory straight away
then rush a morale building
then rush a lab
you need one or two more factories and a bank building to follow (when they get to two turns to finish then rush them)
you have got to keep your population growing otherwise you run out of money very very fast so never send out a full colony ship unless you are low on morale!
The sliders!
Tax go as high as you want until you loose the magic 100% morale and 200,000 happy new citizens per turn
when you have built your first morale building you can put tax higher and get more money without the loss of morale
And for gods sake put your spending on100% even if it means you are in a negative cash flow situation. sell your tech, pray for jackpot anomalies whatever you do keep the spend slider on 100%. I can't emphasise how impotant this is to winning/playing a better game etc
Racial picks
Morale - 10%
money - 20%
planet quality - 10%
research - 20%
with populists as my political party
BUT - This is how I do it .....Good Luck, init
