So I've been playing Minecraft since before the red stone update on xbox 360...
Im on Pc now, and frankly, I'm getting slightly bored of pure vanilla Minecraft, either because I don't have time for the grind, or because I've done this stuff before.
I need a mod that's easy to install, doesn't modify Minecraft too much, keeps the original concept and goal, but adds a bit more to do, maybe side quests, mini bosses, new structures, a few new items and maybe some mobs
If you know a mod like this, please tell me about it...
I'd say try any Vanilla like modpacks to get you started, that way you can find what ones have the Vanilla feel that don't tweak or add tons of content, and if they do they are things like filling in Vanilla gaps like Birch Chests or something that the main game doesn't have.
I know it's not like a list of Vanilla feeling mods but you can tell which ones players go for when they make Vanilla based modpacks that and I can go overboard with mod recommendations so I'm keeping it minimal, which besides going deep into mods, these are great for newcomers to mods or players that don't want much to change or overhaul the experience.
Most mods that do this though that don't add content would be tweak or quality of life like leaves decaying, crafting related, minimaps I guess and a few others, many other content ones do like I said with filling in gaps that being the Birch Chests and other variants in mods like Quark or others like removed features from Minecraft/backporting content from newer updates to older ones, to upgradeable Chests/Furnaces (Iron Chests and More Furnaces) using Iron, Gold, Diamond, Glass or Obisidan (the last two being good for items being visible inside or blast resistance) or adding Emerald and Obsidian Tools (there is a lot of these types of mods, either for those materials or ores like Copper, Silver, Titanium, etc. it isn't funny sometimes, but it's some devs starting mod sometimes and they can be good it, just depends on the recipe and abilities/damage they have I guess). Mods like those are the sort of content I'd recommend to a Vanilla player that uses mods either when starting out or just to keep the feel of the game. Besides realistic mods or something but they I find can be good if you want to go for more mods than Vanilla ones.
Try searching vanilla and seeing what mods or descriptions are given. If you want to tweak any go for it (while these modpacks are made for the Twitch launcher, if you want to stay with the Vanilla one I'd say look at the mods in the packs and download a few or watch videos of people that have covered those mods:
Otherwise though to actually list some mods I'd like to ask the version you'd be playing on. As 1.12.2 is the common one and while 1.14 is great it has only so many options. I am familiar with both and 1.14's two modloaders which is something many people will need to get used to compared to Forge being the one to go to all the time. But only then can I start recommending mods so I can get the names of those types of mods and the links properly instead of putting 1.12.2 ones when you'd want 1.14.
Your welcome, all good, just use mods with a Vanilla feel and you'll be fine, many concepts in mods are very similar to Vanilla but can go more deep when it comes to Magic or Tech usually for many ores, tons of crafting, power systems and deeper elements which are grindy or tedious but worth it in the end for large resource rewards, more efficient/better food production, special tools/armour/weapons, skills, cool spells and so on that you'd expect, that or utilities to assist with tasks where things like farming can be boring but get something to do it for you while you do something else and your good XD so really Vanilla mods are a good place to start regardless that or at least JEI (a recipe mod) or a Minimap (Voxel, Xaero's, Journey) if not adding new blocks and items or gear to upgrade your character.
Many of the above I mentioned were 1.12.2 mods but others do exist for 1.14 but they just have differences/different directions but similar themes/goals or different names.
I'd say if you'd like a Vanilla approach at magic to give you an idea of what I mean would be 'Vanilla Magic' where it uses the achievement/advancement menu to allow for spells and utility features all using Vanilla, it's really smart how they go about it and it has books to assist but no new blocks at all. It's probably a good mod for easing into mods that do that more deeper level of things (crafting in different ways, using blocks besides just tools or building to achieve tasks, magic spells without the grind or as much grind) or similar Vanilla concepts but staying Vanilla.
Either way though, if you'd like I could make you a modpack or just bundle a zip file and you can just put the mods into your mods folder to play with the Vanilla launcher instead of with another launcher just to set things up.
Otherwise if you want to know anything about mods, installing modloaders and so on let me know.
