HS1 is already an obsolete software. Most mod authors, especially paid mod authors, have switched to other games. Nowadays, it's rare to see large-scale mod sharing, especially of paid mods. There was once a Discord server created by some F95 user that shared paid mods, but it got nuked. Even then, there were few HS paid mods; most were HS2 paid mods. HSresolver is a good tool, but it only contains free mods. So, when you are convenient, I hope you can share it soon.You're pretty much dead on, it's 560GB Compressed - I made my own repack backup installation with 9000+ Paid & Unpaid Mods with the latest Plugin's - Unzipped ABDATA on my installation is around 1 TB as of 12/06/2025. You're correct though, Vanilla version is best and D/L mods you want.
I will probably upload at some point when HS1 and the Mods are abandonware. HS1 rocks and I will make sure it survives =D
