Well, I know the Vasari (Phase race) get a "Phase Gate" module that allows you to create Phase Lanes between any two gates. This only lets you travel from one gate to another mind you, and if your map is huge it'll still take a LONG time (which I found out the hard way, lol)...you can also increase the hyperspace speed while going through the phase lanes (at the very least the ones through these gates, from what I could tell at least).
You could mod it so that the gate is available for other races...but you'd have to be careful about placement in the research tree(s) so that it doesn't take up spaces that other research subjects are in.
Oh, I think these gate modules are also limited to planets in the same star system...it still makes things a lot more convenient having them, though!
Oh. I didn't know about the "Phase Gate", but that is probably because I never played as the Vasari. However. this development does make it extremely easy to add a Stargate type device into Sins , since authority exists within the game. I guess when I add it the other races, I could make Phase Gate jumps faster.
However, I do think it would be cool if someone modeled new gates for the Advent and TEC (I think the TEC gate should look like it was stolen from the Advent.
Okay, its been awhile since I messed around with modding in Sins, could someone remind of what I need to do?
