I like tribal stage as my little people could fly and were  a little crazy...some how it made it all so much better.

I reached the centre of the galaxy by flying the whole way - i flew to the edge of the Grox empire, built a colony so that if i died i would return there, flew half way through the grox empire, and made another colony, then flew to the centre - died a coupla times but meh.

Tribal stage is shallow, I liked the Civ stage (not as much as Space, Creature and Cell though)

So stopping the grox from attacking you is pointless. You start off with -70 because they don't like others, you can get +10 from offering them money, +50 from mission completions, and another +20 that you worked for them or something like that. You end up hitting -5 and there's nothing you can do about it. I wish I was steve....

Ack, seriously this thread should have just been called spoilers. Im just glad I caught myself before reading the whole first post. If you are going to talk about the big ending of a game in the first sentence of the first post I think that qualifies as more than "possible" spoilers.

I'll be back when I make it to the center. Right now Im too busy building my 100+ star system empire.
