Perhaps quit playing a war game if you don't want attacked (and on a side note, quit sending "warnings" every time you get probed). Why should someone willing to spend the money be immune from a good beating now and then? Definitely a no from me regarding that idea.
As for the number of systems and galaxies, I think they are more than adequate as they are now. Making them bigger will only lessen the excitement, especially since longer distances eat into profit. That's a second no from me.
And please, Please, PLEASE!!! No Ads. Horrible little things - ads. People really click on those nasty buggers?
As to not totally shoot you down though, Asheron, I do like the idea of techs for more efficient engines - like combustion engine tech, impulse engine tech, and hyperspace engine tech - we should really think about implementing those. Would really speed things up a bit in my opinion.
