Looks like normally drawing mech combat is soon going to be a long-lost art form.
Ah well. I'm much more tolerant of CGI nowadays so this won't particularly bother me. On the plus side I got some FFVIII vibes from that spidercrawler Knightmare so that set of my nostalgia-dar.
It makes sense that the studio is planning more than one OVA. It'd be pretty suicidal for something like this with new characters and storyline, to say nothing of the fact that Code Geass certainly isn't unpopular. I'd be surprised if they limited it to only one single episode, to be honest.
