Finished Clannad. Took me like 1 month and 8 days or so. All routes, all CGs unlocked, etc.
No doubt one of the best nakiges around, 'cause it sure made me cry a lot. Literally crying at times, not just being teary-eyed. However! That only really happened during certain routes/scenes. It's a mixed bag for me. That's kind of expected though because of how many routes there are in total. Can't expect every single one to cater to one's tastes. Some are good, some are amazing, some are... not that good (MY opinion, remember that). So... yea... mixed feelings, and I'm not sure what rating I'm gonna give it. I will say though that the best parts in Clannad pretty much overshadows the "average" parts. So in the end I think it's a great VN.
Some random info from my experience with it:
Favourite routes: Kotomi's route and After Story. Ultimately it's these two that stood out the most for me in Clannad. Kotomi's route was a very big surprise... I just didn't think it would get that incredibly emotional. Absolutely loved it and I would be willing to re-read it at some point. After Story was equally amazing during certain parts of it, most (not all) of which took place during the second half. Also After Story had the best music, which is a pretty big deal.
Least favourite routes: Ryou's & Kyou's. Yep. Kyou's route had a few good scenes, but most of it was just annoying to me. I don't mind the characters at all, but the routes weren't to my taste unfortunately.
Favourite characters: Hmmm... probably Kotomi (because most interesting + waifu), Tomoyo (because cool girl) and Fuko (because funny cute). Though I like several other characters as well and there wasn't any character that I straight up disliked. Nagisa's parents are awesome.
Music: Some of the best emotional songs I've heard in any VN. Don't need to say much more than that. If you've read Clannad then you can already guess which ones are my favourites. Besides those songs though, I really like the one that plays in the "illusory world" scenes, and also the characters' theme music.
Translation: Fine in the main game for the most part. Not good throughout the majority of After Story... mistakes and awkward English all over the place, seriously. Thankfully however it did get much better in some of the best scenes in AS.
Sunohara's screams: 10/10
Mei's "Onii-chan": 10/10
Kotomi's triple question marks: 10/10
Clannad: Dango/Dango
