Winning

This guide I built was garbage. I'm going to do it properly.

Humans - You can win on impossible with humans in less than 5 minutes (speedrunners)! Take a few planets and spam out until the diplomatic council begins and you will win.

Psilions - Get new planets quickly, build tech so you can outclass your opponents and get terraforming online. This way you can protect what you own and get a population advantage.

Klackon - Conquer. Max production, expansion, and research, this should allow you to get enough planets, and your tech won't be backwards. Build small ships and missle craft, ignore planetary/computer research, focus on engines, shields and weapons.

Meklon - Same as Klackon but it will be a bit trickyer

Sillicoids - Expand. Take every planet in the galaxy, focus all efforts on colony ships to take at least 50%. Then, spam a large enough fleet to take the rest, regardless of inferior tech. All tech goes into weapons and shields, engines are worthless.

Sakkara - Same as Sillicoids, can be more efficient if there are more fertile planets, but not if there is more hostile planets.

EVERYBODY ELSE

- You are going to be at a massive disadvantage, especially if your against any of the above races. Redouble your efforts to stay in peace time as long as possible. Don't war if you don't have to. Get your tech up. If you can nab orion that will help as well.

I've always found computer tech is very useful to the Meklon as leveraging their factory output with robotic controls can beat impossible through sheer planetary production.

Doesn't make sense to me so I go with the guy asking for a video. I know it can be done but not sure these "tips" are the key. Bad planets / planet range destroys just about any race, and, quite often the game mistakenly sets the AI you're against at 10 population from the start, so it seems you're winning when you're merely exploiting a glitch in the map setup file.

The black hole generator is a sure winner. If subspace teleporter is added, you can defeat them quickly.

I won on impossible with the Mrrshan, defending with missiles, and scooping up the weaker races. In the late game, the AI is an idiot, so no problem once I got there. Oh, and this was about 30 years ago, so memory? Who knows?

As long as you start with a few decent planets, winning on impossible is possible with most races.
My favorite races are klackons (industri growth), psilons (research), sakkra (fast population growth), Humans (diplomacy) and meklar (huge industry).
I always start with building scouts, sending them to every starsystem within reach. As long as enemy ships entering starsystems orbited by my scout doesn't have any weapons (early colony ships and scouts), they will always withdraw. This way you slow down enemy expansion, and can often colonize starsystems that without your scouts would fall into enemy hands. Sometimes the enemy colony ships gets equipped with rockets in early game. With a bit of luck you can actually outmanouver the missiles with a scout, yet again forcing the enemy to withdraw.
Rapid expansion is crucial! (Continued)

As iceman8309 mentions, don't bother building a fleet in early game (with a few exceptions), but research missiles and planetary shields. Building a good planetary defense is much more cost efficient and often safer than building a fleet. It is very satisfying the enemy throwing wave after wave of fleets that gets obliterated by your missiles. ;-)
Don't bother researching tech that you're not going to use frequently. I find ship repair, torpedoes and biological weapons mostly useless.
If you have the choice of researching two similar techs, for example industry tech 8 and 7, always go for the better one, except if you are in rush to get a tech.

Good luck!

I've won as 4 races on impossible in a large galaxy with 5 opponents. Humans, Psilons, Darloks, and Klackons. Each one needs a different strat. Humans are actually the easiest. I've won in less than an hour.

You expand as fast as you can and snag a half dozen planets. You probably won't be able to get more. Everyone you meet is relaxed with you, so the turn you meet them you get a non aggression pact and the highest trade agreement available. Also try to trade tech frequently. Research missile tech, planetary shields, and robotic controls. Don't bother building a fleet. The upkeep isn't worth it. Build at least 5 missile bases on each world at first (more later). Stay friends with everyone you can. They might vote for you in the first council. Eventually, if you don't get a lucky vote win, you'll have to go to war. Prepare a fleet in advance and hit your target hard. Late game you'll want neutron stream projector and black hole generators to deal with the enormous enemy fleets.

you can win on impossible using the psyloids (research speed race) with good RNG for quick expands early game. then do research, getting planet shields. quick expand ---> turtle. then with enough research you are OP.

I've played MOO tons of time, one of my all time favorite games.
On Impossible - choose silicoid as race, and like the strat says - spam Col. ships and build all you can. Choose 1 opponent and huge galaxy, and you'll get the best benefit, but they game will take you many hours, and your not guaranteed the vic.
Research shielding and get bases on your planet asap - that will keep the enemy away, and you can focus on transportation of people and research terraforming and other stuff. It's tough but fun.

The best and most challeging but winable setup is Large Gal. with 3 opponents - it's tough but game takes fewer hours....hf.
