I've always wanted to play Nocturne but I keep forgetting about it. Thank you for reminding me! I'll track down a copy as soon as possible.
I can't really remember how far into Strange Journey you'd be at 10 hours. Maybe near the end of Boötes? The game gets quite a bit better after that in my opinion (as well as MUCH harder. Boötes' final boss is brutal). But since I haven't played Nocturne I can't really say which I'd prefer.
