This game is not a great its a fantastic game that is worth the full $25 that i payed for it.
I'm aware that the game is $30 now and i still thinks its worth the buy.

To prove my point when I buy most game, I go off the the $1 to 1 hour rule (Depending on what game I'm buying).
If i go off that $1 to 1 hour rule I have well passed $25 now even $30. 263+ hrs (at this review time) to be exacted.

This is hands down one of the best communities ever. The developer's listen to the plays and not just through one ear and out the other (Looking at you EA). They added or talking about adding things the communities ask for and frequently updates the game to remove a bug as soon as its reported. They even post upcoming updates or answers questions that the community have and or just updates us whens happening in their office. The players will also not critique the way you play, they will encourage you, they will give you tips, they will help you (if asked).

Don't get me started on the modding community. They have made mods of the game that can make the game harder or easier or even add some quality of life mods. They're even mod packs that are made to make your factorio life hard like Bobs Angels mods or Sea Block.

You can Sink many many hours in this game and it shows, look down to the other peoples reviews and try and find someone under 15 hrs, Come on I'm waiting.

Cons:
Takes your time away never too be seen again.
Infects you with conveyor belt syndrome where you dream about conveyor belts and the factory MUST GROW!!
(getting off subject there)
You can thing about any other thing to put in the Con section of a review.
