Sorry for the delayed replies, as you may have noticed I've been having technical difficulties with the Sins forum.
Will there be an optional version with increased prices? I mean low prices are fine for the first tier of research, but tier 8 shouldn't be obtainable after just 20-30 minutes of game time.
There's two main things I'm concerned about. 1, that races like the Advent that have a lot of extra prerequisites for ships like the guardian or the deliverance engine would be hit extra hard by making research harder to get rather than just adding more of it. The second is that many techs are already of dubious value as it is, increasing the price more would make them near useless.
If I wanted to make research harder to get, I think it would be more effective to increase the amount of labs required for each tier or make the labs more expensive (after all, a tier 8 tech with no prerequisites could still be gotten in a half hour even if I doubled the price).
(hope you're ok with that)
Sure as long as it's just for yourself, but obviously I can't promise any support with that.
If it's still the lag problem, I've been looking at it but as far as I can tell it's not any one thing from the saves people sent me, and quite honestly I get similar lag on equally large maps in Vanilla anything. If it's crashing, that I'd like to know more about because that shouldn't be happening (well there maybe one crash bug but I've been unable to track it down).
First off, the artifacts research screen is not working correctly.
Yeah, I had to replace every artifact icon and redo the entire window to increase it to twenty. I'm not sure how that would transfer, but you have textures, brush and window files you'll need to track down as well as the entities and string entries you got.
Second, what files do I need to change to allow for the new envoy features?
Well, just the embassies only need the embassy entities and the entities for the abilities to create them I think (oh, and the research for the AI to use them correctly). However, I made a bunch of minor changes to things like the gameplay.constants file and quite honestly I'm not sure what else. So you might notice some differences like the embassies giving more relationship points.
Third, like the envoy, what do I need to change to allow the mines in my mod to behave like those in yours?
The mine abilities and each planet entity file I'm afraid (you'd be best just changing the maximum mines line in each DS planet individually).
