Naval's light pack is a mod pack that allows for advanced tech development while also being in touch with vanilla Minecraft.
It include tech such as quarries, power generators, ore processors, and much more. Generators, turbines, and solar panels can be used to power your machinery. Some machinery can mine fore you, such as the quarry, and others can multiply your ores, such as the enrichment chamber. You could also make machines that can power your tools, such as the jetpack.
For those who like to adventure or fight, there are structure to be found such as dungeons and towers. Existing biomes are greatly improved, while also adding more biomes in both the overworld and the nether. Items such as the waystone allow you to travel to your favorite places in the blink of an eye. It also adds baby mobs for harder fighting. Dungeons have many spawners, some even spawning mobs with enchanted armor, but rewards with chests full of loot.
For the builders, there are added decorative and building blocks to allow the player to let their creativity flow.
With all these mods, the game is still able to run on most setups without a problem.
