I worry about 32-bit systems for the BASE FE.
If you have a 64-bit OS, FE will see 4GB. But if you have a 32-bit OS, you only see 2-GB. If it uses more than that, the game will crash ungracefully.
And (Mr. Wardell) your first sentence, in your Reply #90, has me worried now ... because I am one of those people currently locked into a WindowsXP, 32bit system, for the present. This will not last forever; but it is my situation for the near-term future.
Just to review the bidding, I responded to this survey, originally, by answering that: "I don't currently have 64bit, I don't care." with regard to the question of Stardock making additional down-loadable content (dlc) available, at a nominal cost, to 64bit users. As I stated then, I am happy to see ALL interested gameplayers get the best possible version of E:FE that they can utilize!
I hope, however, that your development team will continue to try to provide a good, working, game to 32bit users. As I have stated a number of times in your forums, in the last few months, I think it would be a mistake to abandon 32bit users, when it comes to E:FE. (On the other hand, if you decide, with your very NEXT game, to develop for (and market to) only 64bit users, I would understand. That way lies the future ...)
However, the 32bit community hasn't become trivial quite yet. The Beta-Testers tend to be the Power-users; but there is still 15%-20% of the larger market that is stuck with 32bit. I really don't believe the percentage is any less than that; especially when you consider "poor" students, casual gamers, and non-power users. You will not be selling many more copies of E:FE to the Beta Testers -- they already have their free copies, and discounted copies. The (larger) community of casual players and non-Power-users is still where a significant portion of your profits from E:FE will come from, IMO.
I have no problem with a "divide" -- I just hope you won't abandon the 32bit community entirely, when it comes to E:FE.
