If you like mechas, inevitably you'll face the "mechas are not viable" reality. After a short period of shame for letting your inner kid dictate what would work in the field of combat, you realize you still like the concept, impractical or not.

Some may try to find the most realistic mecha possible and whatever plot would allow it to exist, others just don't care and just want to jam as many guns as possible on top of two legs and roll with it.

Personally, as long as it looks cool and heavy, and it consitent on its own world I am okay with it.
