Where do i even start huh?

Tectonic has all the features in overhauling the worldgen, by default you get higher mountains, deeper oceans, not strictly a bigger cave system, but definitely a more diverse one, a pretty nice river and other worldgen features, but by far, still pretty for Vanilla+

The kicker however is within the fact that Tectonic is highly configurable amongst many other worldgen mods. You can modify almost everything within it. Starting with world height (both Max Y and Min Y), the cave carvers (the code that carves caves), continent sizes, river sizes, erosion (basically horizontality/verticality of certain features), islands, oceans, ridges.

And on top of it all, a really configurable biome spreading that uses temperature and vegetative parameters from every biome to determine how the overall world looks, that has compatibility WITH ALMOST EVERY BIOME MODS (Terralith, BoP, BWG, Regions Unexplored, Natures Spirit). You can make cold biomes and warm biomes has a certain amount of separation between them, and have biomes with less trees be far from biomes with lots of them, super realistic.

One last point, unlike some other worldgen mods that causes a HUGE performance hit, Tectonic only consumes so little on most of my modded playthroughs (worldheight set to 480 though), it genuinely baffles me on how the devs optimized the code.

But sure it does have a shortcoming in some terms. It basically overtakes the worldgen from Biome mods, making certain unique worldgen noise (the tendency of how the biome's affecting it's land, e.g plains is flat, mountains is rising, grasslands is flat), either completely got overtook, or have only a little effect. Luckily it doesn't affect any placed features like in the BWG Ironwood Gour, BWG Lush Stacks, etc.

Another shortcoming is that while the mod is really configurable, i feel like there needs to be a more descriptive documentation or tooltips in each configurable settings, as right now some players without any technical knowledge may have issues in customizing Tectonic. On the note of configs, i do wish there's a way to safe and export presets that you've made (other than directly copying and pasting the json).

Overall, an absolutely no brainer mod to add into any packs you got. 10/10
