Oh god, Green Green. The 13th episode just decided to give up & throw in a sex scene. Such an ugly looking show.
Also, yeah, School Days was based on a H-game as well. Which is why I say if you thought Makoto was awful in the anime, man, in the games, he's somehow even a worse human being.
Even before streaming became more common, I was just never one to buy videos once gaming became more of a hobby. Granted, I remember having a lot of Pokemon tapes, but that was because I couldn't watch it on TV. As of now, I either want comedies that I know I'll rewatch or can introduce to a friend, Jojo, or One Punch Man. I always had a weird feeling that if you own a series, you have less of a desire to watch it because you can see it whenever you want. It's kind of more fun discovering "oh cool, it's this episode" or "neat, this movie's airing on TV", sort of like playing roulette. It's why Simpsons reruns are kind of fun to discover, seeing an episode you haven't seen in a while, making it more desirable to watch it.
But yeah, Nichijou was a series I enjoyed so much, I promised myself I would buy it to support the fact it was a series I actually wouldn't mind rewatching from time to time. Cromartie High School is another I wouldn't mind owning eventually.
