Tip 1: Choose your construction carefully, you will be penalized if you disrupt it prior to completion.
Tip 3: Colonization is a considerable effort in ISG, do not colonize worlds that are not suited for your species if you can help it. You will have more candidate worlds to colonize than available colony ships initially, pick and choose where to expand wisely. Consider the following: Ideal biome first, tolerable second and hostile last, Try and stay within your gravity preference, Mineral richness, the richer the better, Ecology, the higher the better, Avoid nasty specials like meteor storms
Tip 4: Colony leaders are a big help, hire one quickly and leave the ship leaders for later.
Tip 5: Domes offer a less effective but quicker alternative to planetary engineering on hostile worlds.
Tip 9: If you start at the edge of the map choose the space culture advancement that allows you to scan further away.
Tip 10: If you start at the middle of the map choose the space culture advancement that allows you to scan two sectors at the same time.
Tip 12: Tool tips are everywhere, if you're not sure about something check the information there.
Tip 13: When exploring try and select the sectors closest to you that contain a star system.
Tip 14: To measure distances use the measuring tool by pressing the SHIFT key. Then select two systems and you'll be shown the distance between the two in parsecs. Press your mouse right button (or the Esc key) to switch off the measuring tool.
Tip 15: Support ships are a great way to jump-start production in the early game, you get a free one once you research the appropriate tech.
Tip 16: Maximizing infrastructure on newly built colonies is a great way to accelerate their growth. Set Infrastructure to 100% until you gain a few levels, then you can consider buildings structures.
