*sighs* well Starslayer and I are, hell I only know him because of the starfire mailing list.
It was a defining event alright. I wasn't directly involved. It was painful to watch from the sidelines. I tried to get the locals in München interested in 4th edition but no dice without a starfire assistant replacement. It is sorta the gold standard for this kinda game in my mind. I'm good at EXCEL and I tried with that but very quickly ran into trouble at turn 20 or so of a 4thE solo game.
Yeah, Marvin has an excel spreadsheet for tracking everything in 4th that he, or someone, put a lot of work into, but I could never get it two work to my satisfaction. Which probably says more about my issues with excel than anything else. I considered doing a 4th/Solar campaign when I decided to get back into writing campaigns, but without SA I'd have to put a lot of work into either building an excel spreadsheet myself, or figuring out someone else's. SA just makes it so much easier.
I have to admit I find the "Ai exist therefore the L is useless" an interesting argument given the F faces the same level of Ai plus the shields a ship may be carrying, it just does more damage. I'm curious to see what the sovietski's do when the Wa rears its ugly head. That is a seriously overpowered system once AM shows up. The shanirian's kept the L is service for warp point defense purposes...since stripping XOs was a bonus. I sorta think that the "SM" is part of the problem the W would not be so much overpowered if you had to decide how many "sprint" and how many "regular" missiles will I carry...that you can use one missile for both tasks removes a bit of strategic choice and contributes to making it overpowering. But in many ways I think this may be something that can be laid on David Webers shoulders, weapon systems he liked got special treatment (HETs are the only capital beam weapon that both get smaller but also do more damage and are longer ranged with each generation)...if not David Weber then someone decided certain weapons are the "meta" and all other ones got the other end of the stick.
Well, that right there was one of Marvin's driving forces for wanting to do a 4th edition, that and the problems built into the strategic economic system. He wanted to balance everything to remove chance as much as possible. He hoped that by removing the "only one right path" issue from strategic (and sometimes tactical) starfire, it would become a better and more attractive game. He was exactly right about the balance issues, but in creating 4th edition, and the editions after that, he removed the 'flavor' that so many people liked.
As for the Ai/L issue, the Soviets feared falling behind the Coalition in deployed tech, even though generally they've been ahead in terms of research. They only reluctantly gave up lasers, and when they get to HT 6 they are going to leap on the DeC/Lx combo, which also kind of fits in with their attitude about smaller ships being expendable. The Coalition would never go for a weapons system that might blow up their own ship, not unless things were really desperate.
As for the influence of Weber, I think that's more down to David Weber wanting to tell a story, and being absolutely willing to bend the game system to tell it. If he wants to introduce a new threat species with an exciting new weapons system, he's not going to let a little thing like game balance become an issue.
