Factorio: Space Age Review (Cheeze Wizard)
It was surely a massive undertaking to make a paid expansion that can stand out among the sea of completely free modpacks and overhauls you can download in your client. But they somehow did it.
They didn't doing it by upping the complexity compared to modpacks or time required, but by making new interesting challenges with unique gameplay mechanics that extend beyond simply more complicated production chains.
You will find your factories on each planet to take completely different forms from one another. The hazards and mechanics of each planet are unique and interesting, and more importantly, doable without needing to be a factorio expert. Modpacks are made by Factorio junkies for other Junkies when they get bored with the base game, and as such have a much higher skill floor, often requiring uses of logistics and such that are otherwise optional in the base game. Space Age actually feels like it is something meant to be beaten by a more casual demographic, not in a bad way. The megabase potential is even stronger, but just to get to the win screen, if you can beat the base game (now easier thanks to the much improved map generation that released in the 2.0 update that came day and date with the DLC), you can beat Space Age, and if you enjoy Factorio, you will enjoy Space Age.
Don't bother waiting for a sale, it isn't going to come, buy it already.
