Factorio has deep gameplay. You can spend thousands of hours on it and still have more to learn and experience.

If it's your kind of thing, spending $70 for the base game plus the Space Age expansion is really good value; orders of magnitude more than most games. But if you want something that will give you a few hours of entertainment and then move on from it, it's probably not for you.

There's a free demo which has more than enough gameplay for players to decide whether they want to invest in the game.
