Umm... hate to break this to you, but Taldren is out of business.. which means there will be no future SFC titles ever...
the best to hope for is the release of the SFC series source code.. and so far the only talk on source code is for Empires at War and Orion Pirates... as such, SFC 3 is owned by Activision and it is doubtful if the source code will be released any time soon...
However once the source code is released, and if you have Direct X 9.0c SDK and Microsoft Visual C++ 6.0 with service pack 5, and the current scripting API and Taldren's build enviroment (should be with the source code), then you can edit SFC 3 the way you would like it within limitations that the game engine can handle.
Anyhow, sorry to burst your bubble, but editing the current games once source code is released is the best that can possibly happen.. however I am currently working on revising the SFC 3 moddable game files to where there should be more balance in the stock game, adding BB to the 2 races missing them, and re-editing the models in 3D Studio Max 5 so that the hardpoints on the physical models will fire from the correct locations with the correct firing arcs to make the ships racially diverse...
anyhow, I hope that this helps.. just remember that anything released from here on out is purely an unofficial game patch for any SFC game and should be classified as a Mod..
As for adding weapons, that requires the game source code and the Quicksilver game code.. as such, those resources are not available and so the weapons can not be added to the game currently..
As for the previous SFC titles.. Starfleet Command, Starfleet Command II: Emipres at War, Starfleet Command II : Orion Pirates (stand alone EAW Expansion)... these games were based no on the TV series but on a board game called Starfleet Battles and the game tries to hold true to those ties...
SFC 3 was designed to be similar to the TNG era trek time line at about the time just before the movie Nemisis...
It has no ties with TOS trek what so ever...
the other aspect to the game in which you are referring would be extremely difficult to incorporate into the game engine and the server kit.. All planets can be terraformed, whether it is under a dome or if the planet has it's own atmosphere.. as such, all planets count as resources for their empire, Astroids can be minned, and so forth.. gasses from nebulaa's for propulsion systems.. etc..., all these are not wasted space or dead space.. and enemy ships can do deep recon in enemy territory and so forth so battles if you cross the enemy is very likely... also it would be very boring for a GAME to wander the map for 20 Min looking for a battle when you can have battle after battle.. after all this is a Game and not a TV show...
As for what you are suggesting about Warp Tech.. if you care to look at the game map again.. it is the Alpha Quadrant in Piccards era.. which means all races at this point in time has Warp Technology..l now if it was the Delta or Gamma Quadrant, i would agree with you...
anyhow.. these are things for the programmers on these boards to consider once the source code is released....
Hope that this helps.
