Its probably too late for Elemental since it is released, but given how long multi-core and 64-bit processors have been out, and how common they are now, added to Stardock's supporting-games-in-the-long-run mantra, I was a bit disappointed to discover that Elemental has no multi-core nor 64-bit support. It runs out of memory at the 32-bit max mark, and will tax one core at 100%. I don't understand the technicals, but that tells me the game would run much more smoothly if it could use more than just one of my quad cores and would take longer to hit my computer's memory capacity (4 GB of RAM + 4 GB or so of a pagefile). It won't stop the game from having OOM crashes from memory leaks, but they would be a lot less frequent since it'd take a lot longer to reach them, and when the bugs are worked out, it would provide room for the game to scale.
It would be fantastic if multi-core and 64-bit support might be considered for the 1.1x "expansion," or maybe 1.2x, or maybe the first full expansion for Elemental, but even if not, I hope whatever is eventually in the queue after Elemental will have such support.
On the other hand, there would be some advantages for Stardock to try, at least experimentally, to add multicore/64-bit support to its older games like GalCiv II since that game is a lot more stable, and thus you'd have a cleaner platform to try something new on so the Stardock programmers would have the experience (should I say, level up? 
) to eliminate multicore/64-bit bugs if they applied it to Elemental and future games. It'd really put the money where Stardock's mouth is that they will support games in the long run.
