Early Access Review. Grounded is effectively a survival game version of "Honey, I Shrunk the Kids". It's well optimised, the building system is polished and it's really immersive to play in, with tons of potential. If you enjoy base building and Crafting, there's probably 10-20 hours of that to do, although I'll admit that the story content is painfully short right now (can be done in less than an hour). I'm excited to see what the game will add over time because my brain is full of ideas for this little world. One of the best games of the year so far and it's only been out for 2 days.
The other important point is to ignore most of the negative reviews saying either it doesn't have enough content or that the multiplayer doesn't work. 1, it's Early Access - you're not paying for a finished game; you're paying to be part of a development process. If you expect it to be finished, have more content, or it's too expensive, wait for it to be released. Leaving a negative review is worthless. 2, The multiplayer works perfectly, we played for 5 hours in a group of 4 the day after release. It's one of the most polished Early Access games I've played.
