I'm proposing something different to you this time...
Realistic Church Music! =)
You can test it here: RANDOM CHURCH MUSIC GENERATOR
I know that there are very few video game settings where this can be used, but for all those RPGs where you enter churches and cathedrals, it would fit perfectly!
I've listened to what other video game music composers were proposing and found that their music was extremely ill-suited to accurately emulate the music that you can hear in church.
But there's more... Instead of just composing "static" soundtracks, I've created a Random Church Music Generation Script!!
Inside, you have everything you need for realistic church music: baroque and medieval organs, baroque choirs, gregorian chant and baroque cello!
I will release it alongside the Angels and Demons Asset and also as a standalone asset!
