Don't get me started on battletech.
Though first things first: I like Battletech. It has well defined 3dimensional characters, a compelling storyline and intricate drama. (Kerensky's Blood trilogy will forever be among my classics.)
However:
They stole most of their prominent designs from Macross!(When Harmony Gold bought it, the show was reedited and fused with two other Super Dimensional shows: Orguss and Southern Cross.
Don't know what I'm talking about? - It's ROBOTECH)
Technically the MECHS don't make any more sense than MOBILE SUITSNo, they don't waltz around with hand held weaponry, all of their weapons are integrated. However beside a wide range of chicken walkers their design isn't any more sensible than Tomino's Suits. (Their armor distribution is non-sense. Remember - it's actually Macross designs reimagined) They are way too tall, and way too humanoid to be sensible warmachines.
Granted, the fiction itself is high on unobtainum, however just like Gundam's Minovsky particles there are enough handwavium elements to make any hard sci-fi (or engineering) fan scream in terror.:
-They are powered by a fusion reactor, however it's never adressed what happens to the nuclear radiation. (Yes, fusion is not as bad as fission but thanks to the reaction itself, there
will be neutrons and loose protons all around the place). *GUNDAM on the other hand uses a theoretically truely 'clean' reation.
-Pilots are hot and sweaty inside the cockpit since the waste heat build up. - That's plot device, pure and simple. If a nuclear device started pumping out a reasonable percentage of waste heat where it shouldn't you'd cook before you realised it.
-Mechs have heat sinks and lots of them - however they're all covered up! That's nonsense - no heat sink could operate like that.
As for the whole a thousand years ahead:
-They have worse tech than we do! They don't have cruise missiles for example!
Battletech and Mechwarriror are games with game mechanics.
Just like Freespace it's not the 'real' stuff.
Gundam, Escaflowne, Macross is entertainment and for all their realistic aspects they're the 'real' stuff either.
The most likely and oddly accurate explanation though is the Burnside zeroeth law of space combat:
SF fans don't want to read about the life and times of a nuclear missile, therefore space fighters will exist.
I believe a similar phenomenon exists with mechs too.
Yes, there are niches where they could be usefull - however the all too popular, and unfounded conception that they would be a 'superior' force is laughably out of picture.
