I highly recommend installing OptiFine to increase the performance and look of your game. Some mods have some overlap but I left them in so people can choose the backpack they want from 3 backpack mods, there's not TOO much overlap. Also some Fabric mods like Extra Alchemy would have been lovely but I totally understand why people won't code for Forge. I would have loved to have put some of my favorite mods from 1.12 in but alas, it is what it is. But it has worked well for me so I see no reason not to use it, and I use Twtich for a lot of other things already. I also use Twitch/Forge, apologies to those who will hate me for it. That is why I went with the latest version.

I prefer the mods that 1.12 has but I prefer the stability, performance and features of 1.15.2. And we are both full time workers (both working more than normal during the virus scenario) so I wanted to create a modpack that keeps the charm and awe of Vanilla Minecraft while also adding some key QoL mods, as well as mods that flesh out all areas of the game to make it feel more complete no matter what direction you 'go'. She is not a gamer, so I kept the vanilla recipe book on purpose and disabled recipe unlocks in Quark config. I just put a lot of work into this pack and thought I should share it since we are having so much fun with it. If this post is against the rules or anything please delete it. I play with the bois on an Eternal server so I also wanted to sprinkle in some stuff a veteran could enjoy as well. My wife had never played Minecraft before last week, and I wanted to provide her with a Vanilla-esque experience while also providing a 'what I wish vanilla had been like' experience. Just wanted to drop by and share a modpack that I made this week for 1.15.2 for my wife and I to play together.
