After listening to the RO soundtrack again I must say the similarities are not really that much, must have rather been the immediate feeling I got when listening to your stuff.
I think the soundtrack was what used to always bring me back to this game from time to time...
Mmm. I think it's mostly that they're using the kinda chords & progressions that I'm super fond of. Listening to Theme of Prontera! Purity of Your Smile as well! These are some slow jams. Hahaha, this is amazing. I love that this isn't too far off from an R. Kelly instrumental, and, in the context of an MMORPG... jammin' & grindin'! Listening to a few more tracks, it sounds like there was more than one composer on the team. I'm pretty into these tracks, gonna see which composer this was. Mmm... this white christmas track is sweet too.
