In light of knowing the translation probably won't be done for a while, I decided to read a little of the spoilers you gave. Well, more like just the end.
And damn that's horribly depressing. As if they couldn't just let him live. Why couldn't they let him live?! ):
I still really want to play it though. I liked the Tomoyo Arc a lot, well, I liked the whole CLANNAD a lot. It was pretty good story and all that stuff, and I can only assume it's the same with this one. I shall eagerly await a translation.
I command you all to translate it! Well, the people that can. I suppose I could grab a translator myself and do it, not sure how good that'd come out though.
