It can be rather demanding. I don't even have my own settings near max and crash some times even from things getting a little to much for it.

While they do have quite a few settings that can make it run on lower end PC's I'm not quite sure how a laptop that was not made with gaming in mind would handle.

Not to mention while they have far to many sales they still charge full triple A price when they are not having a sale. So best to wait anyways.

It can also be a huge timed sink. Last night I tamed a brontosaurus and even with our server settings being x2 taming It still took over a real hour. Thankfully it was next to our base so I did other things. Just crafting the resources to try and tame that guy took a fair amount of time.
