It's not modded Minecraft, but close enough that I figure it falls under the "somewhat related" rule:

I've been playing Vintage Story recently, which is a standalone game spun off from the Terrafirmacraft Minecraft mod. Would highly recommend if you're into block games. It takes Minecraft in a more survival-oriented direction that no mod aside from Terrafirmacraft really ever did.

Here's my little homestead blanketed in the snows of winter:

Currently playing the 1.7.10 Blightfall with a friend. We're in end game now. We have almost half of the map cleaned.
Never did get enough power to operate more than a few machines tho.

FTB Inferno! It's really fun and unique being stuck in the nether, and I love how integral MineColonies is to progression

Got back to Enigmatica 2 Expert. A ton of fun

VaultHunters. Its awesome.

Technological Journey!

It's a nice GTCE + Gregicality pack that's more involved than Nomi but isn't quite at GTNH complexity. I'm chipping away at it whenever I'm in the mood.

Chipping away at GTNH. I know it's memed to death but it's legit a great pack! The progression is tuned so well.

Been playing a few weeks on a Infitech FtN server. (GregTech 5u and some others, all tuned to be very difficult, and Lycanites throw in to the mix). Still going pretty good on it, just into MV but I've built out the best LV setup of any of my attempts so far.

Frustrating and Fun in turn

Vault Hunters! I just unlocked Create and I’m trying to learn it for the first time.

I have been playing rlcraft and I am really enjoying. There is so much content in this mod that I don't know about yet. It's pretty hard though.
