tl;dr at bottom :)
Hi /mcg/
So I returned about a month ago to Minecraft (I hadn't played since 1.2.5) and have been having lots of fun building shit and blowing it up, exploring, and killing shit. Unfortunately, I think Vanilla has just about hit its limit for me - I made a huge-ass gate that plays music with the new redstone things, explored the new End and Nether, and played around a little bit with the new Command Blocks. I never did any modding back when I used to play, but it seems like there's a lot of content I could have fun with. I come to y'all seeking guidance.
I'm looking for mods that:
>Breathe new life into vanilla content
I've noticed some things that seem lacking, like a lack of decorative blocks in different materials (marble fences/walls, more wool colors, different wood crafting tables and chests) or maybe more variety in the nether.
>Rekindle a sense of discovery
The immediate wonder upon first seeing the cubic hills around me has dulled, and exploring new terrain or making new discoveries would bring some of the simple joy of playing back to me.
>Add more late-game content
Punch tree. Mine stuff. Get diamond. Enchant diamond. Clear underwater temple. Clear forest mansion. Build awesome fortress. Kill Ender Dragon. Kill Wither. Durdle around with more redstone - damn, wireless with glass and arrows doesn't work like it did in 1.2.5. New World. Repeat. I want more! More armor, more bosses, more challenge, more variety!
>Advance redstone to new heights
I'm talking vast automation, factories, machines that mine for me, better stuff-sorting, more transportation (Minecarts have a lot of potential not realized in Vanilla, IMO), stuff I can't even think of, and make it all cooler-looking.
>Let me prettify my world
More colors of wool, different heights of slab, cutting blocks into pieces, giving sheep tattoos (OK, maybe not that)
tl;dr - I've only ever played vanilla, I wanna mod now, help pls?
