I'm a newbie to Twilight, so when I first tried to start a game with a custom race the 'Tech Tree' dropdown confused me. I opened up Galactopedia, but it's really hard to tell which tech tree would be best of my play-style.
I'm assuming that all of the trees have access to the core stuff (economy and cultural planet upgrades, miniaturization, weapons, defences, engines, hulls) at some point, but the factory and research stuff is race-specific.
Are there any massive differences between the various trees? Important things that are missing, or really powerful things added in? It doesn't look like it from the Galactopedia, but it's hard to be sure...
