For finding samples I always used freesounds.org but a friend of mine recently turned me on to Splice, it’s a good way to get professional sounding sample packs and individual sounds based on a subscription model.
Another cool resource that is free is the synth plugin Vital. It’s somewhat comparable to serum or massive, very in depth modern wavetable synth with a ton of routing capabilities and onboard effects. Highly recommended!
The official runtime is 180 minutes exactly, so actually is 3 hours.
