are you that fucking retarded that you're unable to spot the most obvious ones by yourself?
code geass is written by marketing people, the story is based on popularity polls held among their demographic target: yaoi fangirls and kids. code geass is one big steaming pile of deus ex machina.
first, it copies various characters from shows which have been popular in the past - we got the anti-hero main character from death note, a pretty boy with a sharp mind, and we've got the mecha beamspam wallrun jesus.
but instead of focussing on the actual planning, showing the viewer coherent strategies, like death note did (at least in the beginning), we only get plot-aided success. yu-gi-oh did a better job, because in a card game it's somewhat believable. "I ACTIVATE MY TRAP CARD. I ALREADY PLANTED BOMBS WHERE YOU POSITIONED ALL OF YOUR TROOPS.".
in the first episode, lelouche killed off his brother without caring for him, but instead of systematically taking down the rest of his family, the show focuses on comedy crap and highschool romance bullshit (which gets reset later on - i guess it wasn't popular enough), with as much plot-critical information that it could easily be fit in one or two short flashback sequences.
