Once you have a decently size ground force (~ 6 troopers?), you want to start upgrading them, right? Now ... if you're seeing some concrete threat like Mutas or Tanks, then you'll want a specific upgrade like Blink or Charge.

But ... assuming you haven't found any concrete intel at this point, what do you lay down first, Twilight Council or Forge?

While Forge in itself isn't that expensive, you can't seriously plan to build both Forge and Twilight Council and and have enough minerals / gas left to buy upgrades at both.

One advantage of Twilight is of course enabling High/Dark Templars. So ... how (and when) do you decide which of them to get first?


Question: In Mass Effect 3, I did not get a choice of game mode; is it because I imported a ME2 character?
Answer: If you import an ME2 character you automatically use the roleplaying mode (the one with combat and dialog choices), only if you create a new character do you get the choice in the beginning. The roleplaying mode is the one closest to how the previous Mass Effect games worked, so the game assumes that players that import a character would like to play that mode.
