Yeah, did a couple years back. Had to re-buy it because I was like 11 or something when minecraft blew up and i initially got it and had no chance of recovering all the info I needed.

I owned Minecraft Java and Bedrock. I migrated the Java to a new account and now have two copies of each.

I second Create: Above and Beyond!! I’ve been playing it with a friend, it’s got a fun progression with plenty of processing. Early game is rough— I recommend exploring natural generated structures for iron and stuff before really diving into the automation.

Note that it’s still a fairly “kitchen sink” modpack. The magic mods feel especially slapped on there. It also has computercraft and tinker’s construct, which aren’t really integrated with the main progression. If you’re looking for a consistent style with less complexity to start, it might be worth playing Create 1.20.1 on its own or with a few “vanilla+” mods. Create has a “ponder” feature that can teach you how to use basically every part of the mod.

Vault hunters is a blast, it's almost a completely different game set inside Minecraft. I got playing it when they updated the early game and only just put it down for a bit to play baulders gate.
I especially like making farms for a materials that the mod asks for, even if it's not necessary yet. Just infinite amounts of nearly everything one could want.

massive props to VH, it's an awesome modpack, though getting started can be brutal depending on how lucky you are with your seed.

IndustrialCraft still exists: https://www.curseforge.com/minecraft/mc-mods/ic2-classic

BuildCraft never moved forward past the block ID change in 1.12, but it's still updated, IIRC.

Forestry hasn't been updated in a long time, but with the addition of bees in vanilla there's new bee mods to play with: https://www.curseforge.com/minecraft/mc-mods/productivebees

Logistic Pipes also didn't make it past the block ID change in 1.12, but there are a variety of new storage mods like xNet, Integrated Dynamics, Applied Energistics 2, etc.

My personal opinion is that minecraft modding is a lot quieter than it used to be because Microsoft has been playing down the Java version (the moddable version) and playing up the version you have to pay for addons / mods (Bedrock). But there's probably a lot of things contributing - aging demographic of the Java version, the fact that the mod API never happened and never will, disillusionment with M$, etc.
