Tnarg, yes, 2.0 contains everything from previous Versions of Proportions. You can start with the Version from the Gold CD and just apply the 2.0 patch, or load the complete 2.0, and get the same result.

If you are starting a game against the AI, it might make sense to try adding oleg's AI_general files which he just posted, below.

There's no Proportions tech tree except the Version the game can create automatically. That is, start a game with "allowed to see the complete tech tree" selected; then go to the tech screen and click "tech tree", then "tech levels", then "export".

Mostly Proportions keeps the original tech tree, but adds some levels, and a lot of components available from those levels are different.

Oleg, yes I guess I missed the solar plants in Proportions, and should tweak them. I think it would make sense to remove their mineral-generation ability, because I can't imagine how minerals would be something that could be generated solar-ly. ... Oh, I guess that's the "crystalline" part (crystal = minerals + rads)? Ok, I'll just reduce their abilities, without making them a disadvantage - it's a bit hard though since they multiply output in binary and trinary systems. I think I will add a weaker non-crystalline solar plant, too, that doesn't grow any minerals (the rads would represent solar energy).
