I like the story.

This game can do more than just physics. Its power lies in its ability to simulate interactions between many nodes quickly. Whether it be physics, evolution, neurons, chemical processes, quantum mechanics, or cheese, you just need a programmer skilled enough to make it happen.

This game depends not only on the dev, but on the community as well. I predict that modding will be the future of this game.

It is great for the price. The Heroes & Villians DLC adds a new element to diplomacy and battle.

Also, ZOTULLAH!!!

Destruction Physics = Fun!
Could use some more default living objects, but is highly moddable.

Imagine a realistic car crash simulation, now add God like powers and crazy customization.
A nice amount of realistic cars and props.
Large maps.
Tons of Mods. (Built in mod manager and browser called the "Repository")
You can also change gravity!
Realistic car crashes.
You can customize and upgrade cars.
This is not covering everything.

Performance Wise:
Runs well on recommended specs (I have around the same specs as recommended on the store page)
If you have integrated graphics, it will not run well, but if you have something like Intel UHD 600 or Better on low settings, then it will run fine, just don't expect to be able to play on high or medium settings.
This game takes anywhere around 3 gigabytes of VRAM (I have a gtx 970)
