Disclaimer: I watched the anime first which then got me to play this visual novel.

While I am mainly an anime watcher, this visual novel was great in expanding the Clannad universe for me (which makes sense since animes are based off of visual novels and mangas). I enjoyed every bit of this game and if you enjoyed the anime Clannad you'll definitely enjoy this as well since the anime only goes into depth on one of the potential paths the main character can take (the visual novel goes into all of them which I really wanted to see happen just as a "what if"). Try to catch it when it goes on sale though, the price is a bit steep.
