I couldn't find a 1.17 modpack that had everything I wanted, so I decided to throw together my own. This modpack adds a bunch of new armor, weapons, biomes, structures, blocks, world generation variety, quality of life improvements, a mini map, and some light RPG mechanics. It also improves upon the Nether and the End.
Some of the included mods are:
AdventureZ by globox_z
Lakeside by juicebus
YUNG'S Better Strongholds by yungnickyoung
YUNG'S Better Mineshafts by yungnickyoung
Fabric Waystones by lorddeathhunter
Trinkets by emilyploszaj
Castle Dungeons by pufferfishpl
Roughly Enough Items by shedaniel
Dual Riders by flytre7
Repurposed Structures by telepathicgrunt
Atmosfera by hephaestusdev
Expanded Storage by ninjaphenix
BetterEnd by paulevs
Origins by apace100
Origins: Classes by apace100
Inventory Sorting by kryptonaught
Simple Backpacks by kwpugh
This modpack seems to run good on most systems, so I would say that 4GB of RAM dedicated to it would be enough.
None of the mods in this modpack are my own creation, and are under under the ownership of the individual mod makers.
