For my first game I did a small 'cakewalk' scenario and quickly had about 30-40% of the galaxy. Lots of research, made good ethical choices, researched all 'influence' items. Build LOTS of embassy and lots of 'Influence Starbases'. I'm trading with 4 races.
The 'Influence Starbases' don't seem to change my influence. And eventually, the YOR come along and clobber me, no matter how much everyone else loves me. I can't ask anyone to attack the YOR, because they are not listed on the 'ATTACK' list of races (why not?). It looks like even if you stack the deck incredibly in your favor, you've got to have guns and butter and might as well not even bother with embassies. Embassies don't really seem to help (much like 'Influence Starbases').
Also, since I"m so great and everyone loves me, why doesn't anyone join my civilization? Or why can't I make a treaty offer for them to join me?
Any comments welcome.

PS: I'm probably about 5 hours into this 'learning' scenario. Geez, this is a LONG game.
