Oh, not at all, I was just slipping in an underhanded comment about my own perception of formal/classroom foreign language education, and how it probably won’t be sufficient for playing Saihate no Ima no matter how many semesters of it you take. =P Are you sure you don’t want to have a go at translating that into English, though? Just the first line will do.
As for the ‘subtleties’ you mentioned, I argue that they are not really subtleties. I think you’re just overanalysing. Yes, while ??? carries more of an inquisitive tone than e.g. ??? it doesn’t necessarily have anything to do with wanting to know the details behind someone’s free time… the asker could simply be being polite. For example, in G???:
Kyosuke isn’t asking anything here… I think you’ll find there’s absolutely no implications behind the ??? whatsoever.
That’s just one example, mind, but I don’t consider these things worth noting unless the context requires it.
