Hmmm different it is sth combined from Dominion Wars and Homeworld but it has awesome full Direct X 9.0c support and above avesome (May I say terriffic graphic interface - all screen capture films use graphic engine + 3D Solar Systems display + 3D Galaxy display etc.). Everything there is in 3D. It also has fantastic lightning environment (better then StarWars Galaxies or X-wing Alliance). It is fully modable game. SFC was not fully modable because of for instance: Sprites.q3 files etc. This game is awesome.
Every MOD you create there is entirely packed into different folder. They can be switched by the game engine while starting the game. So you can have for example: ST:TMP MOD ST:TNG MOD Battlestar Galactica MOD with different Solar Systems, sounds, ingame images, models, maps and missions etc.
I suggest you give your PC with atleast:
1GHZ Pentium or AMD CPU
Good or very Good FPU (Motherboard with AGP x4 or x8 or PCI Express)
328 or 512 MB SDRAM or DDR RAM
ATI Radeon 9600 Graphic Adapter
With such PC you can easily MOD this game (remember this are minimum requirements for the game to work smoothly).
I really enjoyed playing Main Nexus Single Player Campaign. Great plot and fantastic missions
