I have bought TI3 + expansion and I want to make a 5-6 players play with newbies (me too I'm newbie)
Which races I should take and which rules I may use???
Should I use all the cards of the expansion, only Imperial II or what???
Thanks in advanced.
My suggestions are as follows. The simpler the better for your first game or it may take you 12 hours.
Do NOT use Naalu, Saar or Muaat. Naalu and Saar tend to confuse first time players with thei racial abilities. Muaat is just plain hard to play until you ahve a handle on the game.
Good races for beginners: Sol, Norr, Letnev, L1z1x, Hacan, Mentak, Winnu (remember Winnu's racial abilities, they are easily forgotten)
The other races are alright, but a tad bit tougher to play.
Expansion Strategy Cards (Bureaucracy is generally better, but Imperial II can be fun)
Expansion Objectives (Gives more warfare related objectives so there is less "turtling")
Wormhole Nexus (You may forget it's there, but this is a key addition to the game and should be included. Note that it is NOT needed for the Keeper of Gates SO)
Artifacts (Adds more VPs which makes for a quicker game)
Voice of the Council (Optional, I don't like it personally, but it is a good addition to the game.)
Sabotage Runs (Just because they're cool. I never see anyone actually do one.)
Racial Techs (These balance a lot of the races that were underdogs in the original version.)
Whatever you do your first time playing, do NOT use Simulated Early Turns. You may find you have a liking for it later and that's all fine and good, but the more playing you do the first game the more you will learn.
Good luck and have fun!
