Now that I’ve read some of your posts on other threads, I’m getting the feeling that you are a beginner. If I’ve misunderstood feel free to ignore all of what I’m about to say.
This game will be too hard for you.
Reading is hard. If you’ve not read anything before, even simple stuff will be hard. Have you seen the book clubs yet? The Absolute Beginners Book Club has just started a new book. You might want to look at that, because this club will be a lot more difficult.
When I said the vocab sheet is “pretty thorough,” that’s because myself and other people in the club are updating it as we read. Printing it off in advance is not really feasible as it is being updated. Personally I am not putting in words I don’t need to look up, so it is not “completely thorough.” You would still need to look up words that were not added to the sheet. There is no furigana to help with lookups either.
How are you with grammar? My own grammar knowledge isn’t quite good enough for this game. I’m getting by on fuzzy understanding from how well I know the localisation. Verbs in the vocab sheet are in their dictionary form, how well do you know conjugations? Characters can and will use slang versions of grammar which are even more difficult to look up.
This game is not short. The opening scene is 2799 characters before you can save. (I counted.) Do you have the reading stamina for that? I don’t. Are you prepared to spend multiple hours on multiple days for this?
If you’re really motivated and wanted to give this a try anyway, I’m not going to stop you. (I physically can’t even if I wanted to.) But I would really recommend thinking about if this is the right level for you before you spend money buying a game you can’t understand enough to play.
You are more than welcome to post in book club threads even years after the club has finished, so if you’d like to return to this later when you’re ready, that’s more than fine. I just got the feeling that you’re not ready yet.
I apologise that this is harsh. I haven’t yet figured out how to be nice without losing the message so I err on the side of bluntness. Good luck with your studies.
