Back when I first talked to Gavin, the OP, we discussed continuing the story line. However, as it seems Nathan is protective of the actual Ares Universe, I would agree that it would be better to port first, staying within Nathan's good graces so that this project isn't boxed by either him, or Ambrosia.
Having said that, I think we should consider a 'neo-port' option.
This 'neo-port' would include the following;
Ā The first and foremost goal would be to port the code over to OSX, allowing it to be played natively on a modern computer.
Ā On top of that I would suggest - provided Nathan allows it - an upgrade to the graphics. It seems to me we have a number of artistically inclined people here, I myself am a professional print and graphic artist, so the world of graphics is no stranger to me. And we can make all the vessels 100% the same as the legacy ones, but with greater detail, the same with the planets, the marines, etc.
Ā Additionally, I would recommend some game tweaks, like ToLazyToMakeAnAccount stated. I too was annoyed when my Cruisers ran out of energy, and I swore there had to be a way to refuel them.
Ā Minor eye-candy upgrades, things like when you board a station, have some obvious battle happen on the inside (like compartments decompressing, and bodies ejecting into space), planets slowly rotating, visual damage taken to the ships, etc.
*Another idea would be to modernise the games ability to play multiplayer. GameRanger is still alive, and made the transition to OSX, so if Ares also makes the transition, we should see if we can maintain the games ability to utilise the GameRanger service.
These would be my suggestions. If we have enough people who are graphically inclined - and the permission of Nathan - then I don't see at least a couple of my ideas being too far out of the realm of possibility. As for modifications to the game engine, whoever is doing our port for us would need to be willing to take on this undertaking.
Finally, as Lord Commander Anic said, we should also leave the possibly open for add-ons to be added on later.
