I just watched Project A-Ko on DVD yesterday.
Hilarious story, likeable characters and so much parody everywhere (without the need for the audience to have seen the parodied references). Is this where Gunbuster got its idea of girl schools and mech training? The animation is pretty good with lots of smooth scenes, impressive tracking shots over towns, mechs and spaceships, battles, etc.
You won't get this much hand drawn animation out of today's anime.
