I like it, even though half the ideas royaly screw my playstyle. Way too many ways to prevent culture flipping.

Non aggression - reduced influence flip ability (not entirely blocked), requires breaking like current alliances. No planet spies (assuming that's still in).

Mutual protection - same as current alliance, requires non agression

Military (support) alliance - as listed above

Economic bloc - requires at least three civs; trade bonuses, additional trade routes between members, and about half the current value of econ treaty per civ.

Cultural exchange - again, reduced effectiveness of flipping (more so than non agression), otherwise I love it.

Scientific cooperation - I'd split it. I prefer the current research treaty setup, but maybe with an increased chance of stealing tech from the treaty giver. The sensor data should be something like this: you can trade it to anyone, for a per-turn price. Making 10 bc per civ per turn to sell my sensor data, where do I sign up?

Co-prosperity - pass, it's just too overpowered, and as currently set up would actually penalize you for getting unification.

Unification - Better than the current diplo win, I guess. Harder, anyway.

how about the AI being able to leave the up.  as stands if the up votes for something like 8 pieces to a starbase.  You just have to quit and then you have a huge advantage over the AI.  And all you have lost are a few trade routes.

I understand Zyx had something like this a few pages back: https://forums.galciv2.com/328231/page/17/#replies

Actually, there is a slight problem with multi-tech system: if you research tech A, that takes 2 turns, and tech B, which takes 4 turns, and you research them one @ a time, you get tech A and its abilities in 2 turns; then 4 turns later (6 in total) you get tech tech B's abilities. If you have them researched at the same time, you get no bonus in 2 turns, and instead you only get both bonuses after 6 turns, and nada within 2 turns. So it's already more economical to research one at a time, and if you add an extra penalty, it becomes even less useful. Now, if you had a tech que, that would be interesting...

One thing or two that I find wrong, is the ability of the flagship/survey ships to see anomilies in the fog area and astroid miners to see astroid's in the fog.  I really don't think that this should be done.

The flagship/survey ships should be set to remove the fog of war and when they see an anomily then go for it. 

The astroid miners would have to wait for astroids to be revealed or given sensers so that they two could scout for their own astroids.

Fog of war? I want it grey (or with optional colors by choice!) like the minimap... but it makes sense that the whole unknowns must be detectable or revealed in a realistic manner. And yet, the point in racing for anomalies is that who gets there first -- how would your small space be fun to explore with continual control over directions. Random luck is also enjoyable.

By 50+ turns on Medium maps, everything has been revealed anyway.

Although I realise that it is important from the strategic side, the idea of fog-of-war hiding planets is quite rediculous. Here we are, hundreds of years behing Hyperdrive, and we already have telescopes capable of detecting Earth-like planets in other star systems! Granted, the data is hundreds of years out of date, but unless they get hit by something large and heavy, or have sentients with nukes and bad tempers, planets don't change that much in 100 years. I know that if we could see which planets had good PQs before we colonized, strategy would be nerfed, but I would like to see some sort of in-story explanation as to why the FOW hides everything.

We might be able to detect them and maybe soon see them.  But we won't really know if we can live there until we go there.  and the game does have steller cartography which lets you see the planets on the mini map.

Well, okay... if it's good for Stellar Cartography (very early tech, btw) why would fog interfere with detection "factors" for all map sizes?

-- Sensors and range from your territory. And how you need to increase it.

-- The surprise effect. In a game.

-- Exploration. GC3 would simply become a 3X.

I would like to see stellar cartography be an improvement as opposed to a tech, as catalogueing(sp?) planets is more grunt work than cutting-edge technological research.

Wouldn't hurt. Besides, "Globular Cluster Civilizations" probably wouldn't sell very well.

would rather have something like spore's
