At the beginning every player is automatically assigned his/ her home planet to start constructing buildings there. But that does not suffice in the long run to keep up with other players – if you do not develop new planets, you will notice very fast that you will stay behind the other players. Although the creation of new colonies is very costly at the beginning of the game, it gives a good return again. More planets means more mines and more planets from which your fleets can go on raids, which means a bigger raid area. That is why it is important to research the astrophysics as soon as possible and also the colony ships to expand your empire gradually.
How to colonize planets?
To colonize a new planet you need a colony ship – a special unit, which has only that function. However to build it you need the impulse drive on level 3, and the cost of 10.000 metal, 20.000 crystal and 10.000 deuterium to build a colony ship are far from cheap. Anyhow it is profitable to save the appropriate amount of resources early to build colony ships. To colonize a second planet the astrophysics must at least be on level 1. For each further planet you have to research 2 extra levels of that technology.
As soon as the needed level of the astrophysics is done and a colony ship is available, you can look for a position in the galaxy view to colonize. It will only be possible if there is no other player in that position, hence the line is empty and if the level of the astrophysics suffices for this position (with level 1: 4 – 12, with level 4: 3 – 13, with level 6: 2 – 14, with level 8: 1 – 15). If you have found an open slot you will have to select a colony ship and to send it with the mission “colonize” to the coordinates you have chosen. Normally you have to be patient for a few hours, because the colony ship is anything but fast.
As soon as the ship reaches the coordinates, one of these three cases will happen according to the given situation:
- The position could be colonized and your empire was expanded with one further planet. The colony ship disappears; instead the common resources for the start appear on the new colony. Resources, which have been picked up additionally by the colony ship, will also be credited there.
- Another player has already colonized the position you had chosen or a planet has been abandoned there quite recently. Your colony ship will automatically return home and is soon ready for a new try.
- You do not have the needed level of the astrophysics so the colony ship returns in vain.
What do I have to bear in mind?
Every new planet costs a colony ship, at the beginning of the game that is first and foremost none too sparse. That is why you should maintain every planet as a start at that time and build mines to boost the your economy. As you colonize new planets, take note of the amount of fields it yields, most of the players define 200 fields as minimum level. Henceforward, every new colonized planet which does not meet your requirements, should be abandoned immediately – indeed you lose resources, but the damage which would be done by keeping smaller planets is much bigger in the long run. After destroying a planet, an asteroid field occurs at that place, which stays there for 24 to 48 hours and bans that position for colony ships – after that you can send a new ship there and try your luck again. The deletion of asteroid fields always takes place at 3:00 am server time.
Which position shall I colonize?
Planets at the outer edge of the solar system will have less planet fields and they will have lower temperature. Positions 7, 8 and 9 often become most usable colonies. However the size of a planet is random and you can't know the size of your new planet until colonization is complete.
But there is another reason why the position of the planet is important. Try to imagine that the fixed star (The Sun) of the solar system in OGame is on position 0, while disregarding the distance. The closer to slot 1 on galaxy view, the closer the planet is to the sun. The outcome of this is a difference in temperature and because of that, two important attributes for a decision are the result: the energy production of the solar satellites and the production of the deuterium synthesizer. The closer the planet is to the sun more efficient the solar satellites can work and that is of particular importance to achieve the necessary energy for the graviton technology. But also miners or other players, who count on that energy source, will have problems with a halved production. To balance those cons: the colder the planets are, the more the deuterium production is boosted which are slots 9 to 15 and are suited better for the production of that worthwhile resource.
Colony sizes and temperatures
Below is an empirical investigation into colony sizes and temperatures. The given temperature is always the second number shown on the ingame overview screen; for example if you had "Temperature 7°C to 47°C", 47°C would be used.
