This has been on my shortlist for over 2 years now, and I'm really tempted to get it. A couple of questions if anyone can answer them...
- how story driven is it (can you ignore any story and build everything when you want to)?
- is the world/landscape the same every game, or is it randomly generated providing a different game each time (a bit like Minecraft)?
You can choose the Creative mode option which allows you to build and explore without any constraints whatsoever. It takes the purpose from the game, and I personally played it for about 15 minutes before I was bored simply because there is no end goal because you already have everything available to you in the game to build without the need to gather resources.
Then there are three other modes, Survival (gather resources, build, manage oxygen, water, food, health etc), Freedom (gather resources, build, manage oxygen and health) and finally, Hardcore (perma death, gather resources, build, manage oxygen, food, health). These other three modes really make the game better
