In series’, music is often remixed or uses a band contracted to the company, two examples of this include Final Fantasy, and we all know the victory theme, mainly because it has been in use since the very first game and has just been remixed.
The other example is sonic the hedgehog series, while i must say the quality has been decreasing, the music always seems do well, most of the games in the latest generations use the band Crush 40 an in house band at sega, and have a unique style which can be used to familiarise with modern sonic games.
I have to say the key sonic moments in my gaming history, well most of which are from sonic games, an apparent one would be the finale of sonic adventure 2 on the dreamcast, hearing the main theme blasting through my speakers as I dash at a giant space ship monster in space is a thing of beauty.
Actually most of my favourite music moments are sonic endings , here’s another of my faves. The part I really like is at 1:49
Instrumentals really do hit home for me sometimes
As for good times, I honestly have no idea, atm while I listen to it I think of GmTV, which reminds me I need food......
