I'm new to mecha. What should I watch?
I like this thing.
Watch "Zettai muteki Raijin-Oh", it's very funny! The only bad thing about it is that the official English release hasn't been uploaded anywhere yet and there is no other translation... I watch raw episodes.
If you can stomach older animation and 75 episodes then Dougram. VOTOMS, 80s Macross, Full Metal Panic, Argento Soma, Nadesico, Zegapain, and Gundam 08th MS Team and 0083. I want to recommend Linebarrels of Iron too, but the first half is extremely annoying and if you aren't into ecchi it can be fucking obnoxious.
