ACII is the pinnacle. The camera panning back on the title screen after you climb the tower in Florence with Ezio's brother and "Ezio's Family" kicks into high gear.
Then later on again during chases throughout Venice.
The ambient stuff is absolute perfection. I recall just sauntering around the rooftops of Venice and Florence with the gentle sound of the city life in the background while the music layered on top. Venice was especially charming. Probably my favourite gaming memory and I can't believe it was 15yrs ago...
Those first three games (AC, ACII & AC:B, though ACII in particular..) just wouldn't be what they are without that score. The atmosphere and charm of it all; half of it is the music.
For any other fans:
Wasn't sure if it was a bug or whether "Home In Florence" was meant to play while in Venice, but I recall it coming on (alongside "Following Cristina") while I was on a rooftop in Venice at night looking out across the Grand Canal and to the buildings across the way. There was the odd distant firework, the moon was casting light perfectly over the environment and there was the gentle sound of a carnival off in the distance. I just kinda lingered there for a while. I don't think that moment has ever been matched in gaming for me. As mentioned above, the atmosphere and charm; compounded by the perfect music.
I hope one day that it (as well as ACI, AC:B & AC:R for that matter) get/s a proper remaster with cutting-edge, remake-level visuals, all the music in place, tighter mechanics and most importantly, the presentation is super-faithful in every respect. I've wanted to go back and revisit classic AC with ACII in particular, either as it was or on the half-arsed remaster, but I fear it'll underwhelm and that if it doesn't live up to what I recall it'll leave a stain on an otherwise sacred memory. As the games exist or existed, I think it might be best left in the past. But an artistically faithful remake might be the right way to revisit it; as I'd know going in it's something different and the original will remain untouched in my mind.
Oooft, the nostalgia...it hurts.
