As has been said, Moon and Terra are the true routes. Moon unlocking after completing all the heroine routes, then Terra after Moon. Rewrite is my favourite VN so I don't really have anything bad to say about it, so take my opinion with a grain of salt.
 
I enjoyed all the heroine routes, some more than others but each of them were engrossing and emotionally charged. I also liked Moon despite it's technicality, my first time through it did have my head spinning at times but subsequent readings made it easier to understand and thus, enjoy. It's worth trying to understand Moon, I don't recommend skimming through it. Terra is quite different from the previous routes and it is good in it's own right. Hope you enjoy it at least half as much as I did. ^^

Hey there, welcome to Fuwanovel.  
 
I disappear for one weekend and I get back to find so many in need of welcoming. =D

That's nice, but what we really need is a translated port. Clannad is pretty well known as an anime so having an officially translated port for Vita would be a good introduction to VNs for fans who didn't know the origins of Clannad.
 
 
The art initially put me off reading it too but I'm glad I did, after a while I never really noticed the weird proportions, ridiculously pointed chins and miniature-triangle noses. Too busy laughing at Sunohara or crying at Ibuki's wedding. Still one of the most heartwrenching moments in my anime life. T_T

I generally liked Kotarou, I found him quite entertaining in Common but his change in Terra was equally compelling. That said, there were points in Shizuru's and Lucia's routes where I just wanted to hit him, especially towards Lucia's end. XD
