This is a modpack centered around this nice mod - Futurepack.

I included some mods that don't interfere with main mod but make your game much more convenient mostly building/decoration, storage and UI.

Realistic Terrain Generation included - use new game generation options.

Modpack is pretty lightweight, so it shouldn't be RAM-intensive.(around 2.5gb RAM while testing).

If you don't know how to start, here is little help from the developer of the mod.

At first you must find an "E-Scanner", which is placed in our dungeons. You can see them often if you explore the surface of the world, you will recognize a metal tube in the ground.

In one of the chests you should get the E-Scanner, so let's look at this piece of technology (use it with right click). In the shown GUI you can see some Information about the block you looked at and 4 buttons at the left side.

The upper one is to open the Tech-Tree, by click them you will get another GUI. In the Tech-Tree you can switch through different pages using the buttons at the left side. The main area can be scrolled (drag and drop) and is filled with Research entries.

In the upper tow pages are some entries that has color and name, click them to read their texts.

You should find there all further information, so here only short what is to do now:

You should run around with the E-Scanner and right click blocks and entities to get a match for every of the 12 Aspects.

Hint: The FuturePack generate bubbles filled up with crystals in the ground.

If you found them all you get new Research entries ... read them and have fun with further researching.
