guys is plural spoon, I was referring to to both sides. End of the day you are arguing over the merits of 2 fictional settings like it actually matters and it's clear neither of you are going to convince the other so can you both agree to disagree before the mods and admins take action?
I'm as calm as I can be, I'm merely trying to hold a discussion. I'm not the one suddenly breaking out in swearing when contributing nothing to the discussion itself. As long as everyone can remain civil there should be no reason for a mod to step in, no?
If you were listening, he pointed out only a number of novels.
That's indeed all he did. Point out the number of stuff and say that this equals plausibility.
The number of sourcebooks, objectives books, technical readouts, era reports, historicals, and half a dozen others that I don't really care to name at the moment exceeds 300. Sourcebooks by definition flesh out and lend plausibility to the setting. The Objectives series in particular is a wonderful point to bring up, because it actually documents and gives a brief description of all major production sites, what they produce, how much of it they produce, and where they send it. That's just one part of the flood of BT background and information.
BattleTech has a well explained economy; socio-political balance of power; and spatial geography;
Aright, fair enough.
and, probably most importantly, well-defined and internally consistant behavior and physics
I'll grant that Gundam can be shaky in that department. But this is of course mostly because of the different animator teams behind each show and the many years inbetween said shows. I could of course point out that the battletech cartoon did some very very lulzy things with the physics in battletech, but that would just be a low blow.

In any case in this department its comparing apples to oranges. Because battletech has close to nothing in the animated tv show department
I fail to see how Gundam can even compete on the grounds of plausible explanation.
You fail to see because you are not looking. Taking UC and the one year war, there is plenty of stuff around that details how the politics between zeon, the federation and the colonies revolved and production centers and whatever you just named. (The game Giren's Greed has a truck load of data in it) Both are credible settngs if you can accept the magitech that drives them. Just because there is
more of battletech (more factions, thousands of planets) doesn't make the setting
more credible than gundam. If anything, gundam is closer to home as it pretty much never leaves this solar system.
I'm just gonna sum up this converstation in a silly matter. "This setting with flying pigs is more believable and realistic than this setting with flying hogs because it has more books detailing how and why the pigs fly"
"Yeah well, the flying hogs also have a bunch of books detailing why the hogs can do **** in the air"
"Flying hogs break my suspension of disbelief, flying pigs are more plausible!"
"But either way, we're talking about flying pigs and hogs. None of which are remotely believable when you apply realism to it."
"Doesn't matter, my flying pig setting has books greatly detailing how and where the flying pigs are bred, thus its more plausible."
to put oil into the Flames
I'm thinking Heavy Gear from "Dreampod 9" is most realistic Mecha Game 
Heavy Gear 2 on the PC wasn't also bad.
I fondly recall playing the demo of one of the two Heavy gear games. After leaving the starting point I ran into some infantry. Said infantry somehow managed to one shot kill my gear by hitting my cockpit or something... with small arms fire.

T'was a fun setting though, just a little hard to get much info about it. Not nearly as well documented as Battletech or whatever. My greatest exposure to it was some cgi/cartoon that was running on tv here. I've tried to track it down on the internet but unforuntately found nothing.
