You're the gift that keeps giving! I use soundfonts from earthbound and Pokémon diamond/pearl lol, I make synths in vital, have used the power drums, lots of stuff from labs, there's a the sine player that Berlin orchestra runs in has stuff too. Got Kontakt but nothing from there took my fancy yet. Going to keep coming back to this comment I think for my next project! Listening to your soundtrack now!
Update, the soundtrack is incredible, anyone reading should check it out immediately.
