Reading this thread gave me the conviction to join the metaverse, because it is true - even if you're a great debater and have good things to say, having some nice metaverse stats can show others how well you know the game mechanics, and thus how much faith to put in some of your posts.
Anyway, having heard lots of people here talk about their strategies, I figured, what the heck, I'll try a suicidal game -that will look nice on the forums
Sure of myself, I used the human race, modified to have as good diplomacy and economy as possible, and started the game.
It was hard! I only managed to keep up with the other races (despite having some good planets) by using my diplomacy to play the AIs off against each other, and by doing lots of tech trading. Throughout the game, I was ahead technologically, but was behind at pretty much everything else. In order to win I got the last two remaining races to go into a bloody war against each other which distracted them long enough for me to grab a technological victory.
Now, I'll be the first to admit that a tech victory is kind of cheap, but I think I've learned enough about the AI in order to go for a conquest victory next game. If not next game, then the one after that. Diving in head first is definitely the best way to learn.
If it weren't for the metaverse, I would probably never have even tried playing at any of the upper difficulty levels.
