So I read the wiki entry on how to decide whether your playing the right difficulty or not. This is rather important to me due to my OCD and the fact that games take a long time. I really hate starting a game and play for 5 hours just to notice that it's to easy (If i stay alive for 5 hours then there is no such thing as "too hard"

)
Now in that entry it says that the game is supposed to be the same difficulty pretty much the whole time.. So if it is too easy after an hour maybe you should restart.
Is this still true?
Now just to get this out of the way: I'm a TBS fan so I play with the pause option and I even (first time this game) turned off the Auto AI progress.
I understand this makes things alot easier (or at least there is not so much a sense of urgency which gets to me) so to compensate I I'm currently playing 2 level 8 AI's (Although fairly easy ones: Tank and Teleport Turtle) on a 120 planet map. I play with schizophrenic AI's, Unexplored map, Extra FOW and Ive hit the 2:30 mark and so far not having a problem at all (as in it's been extremely easy so far). The AI Progress is 137.
I don't think the auto AI progress is a big deal at this stage (It would only be up by 30... And in past games I had it at over 260 without it being much harder)
Ok so what I'm asking is: Does this get harder as the game goes on? Is the wiki entry bogus and the game is just easy at first and starts getting tougher and tougher once the planets start to fill up, waves get bigger and the AI's tech goes up? Is border Aggression going to make the teleport turtle into any kind of challenge?
As said I'm tired of starting over (Ive done it about 25 times...) but I also dont want to waste my time with a super easy setup lol
Btw I tried this setup twice before only I tried a Mad Bomber AI.. The first waves were all around 800(!) ships... Using the tank AI the waves are around 120...
Uhm... Isn't that a bit extreme of a difference? It just makes it EVEN harder to find a fitting difficulty

I'm absolutely loving the game so far but the only thing that is putting me off is the fact that I have really no idea how to set it up ^^
edit: On a side note... I'm running a 2.3ghz Dual Core laptop with 2.75 (usable... whatever that means) gigs of ram.. Am I even going to be able to play a 120 map till the end or is it going to get out of hand? I'd also hate to find the right settings just to have to stop sometime before finishing due to a quadrillion ships lol
