thing is that i don't see a.i.'s making good use of the AF mod, while we can make ultra efficient ships with that mod.
You say that like it's a bad thing. That's part of the fun of Moo2. Let the AI be content with the humongous racial and difficulty-level-based advantages it has. Let the player enjoy designing awesome ships, especially in late game.
I mean... you already nerfed Analyzer, what next, nerf HEF to 25% and make Hyper-X take 40% ships space? There's gotta be a limit to how much we're willing to hold the computer's hand at the expense of nothing being awesome any more.
Edit:
To be clear: I am in favor of unnerfing pretty much as a matter of principle, but in terms of objective game balance, I don't think a "good" solution exists either way, as long as the computer doesn't know how to tech and pretty much never builds high BD ships. It's either going to get screwed over by powerful player-built Autofire ships, or it's going to screw itself over by building Autofire ships which then miss against the player's high BD. Well, maybe that latter possibility is more common with me, since I play early beam/stabilizer ships often, and I get the impression most people don't do that...
If you could find that offset, I think your nerf PLUS changing the penalty to -10 would be fine, though.
Edit2:
I am reminded of
Sulla's review of Civilisation V:
The game balance is marginally better after the patch, but it was achieved by relentlessly attacking player strategies that proved to be effective. It works, sort of, but is it fun? Not really.
This is kinda our situation here. The underlying problem is that
the AI doesn't know how to play this game. You simply cannot truly fix Moo2, no matter what you do to the balance, without fine control over what the AI does, especially how it techs, the kind of control I imagine we won't have unless the code gets released. The path to making the game easier for the Ai inevitably involves nerfing into the ground every fun and awesome strategy the player has at his disposal. And I don't think it's worth it.
