Stormworks: Build and Rescue

IT IS GOOD FUN

300 hours in just 6 weeks. It's good. A sandbox for vehicles with some Lua coding. Supports all, underwater, water, land, air and (with DLC) even basic space flight vehicles. All DLCs add value except space DLC. That one is not really worth it imo. It once was meant to be a rescue simulation, but it's more a vehicle building sandbox. The procedural missions are basic and not more than an afterthought, so it's mostly a vehiccle creation sandbox. 90% creating, 10% using your creations. Multiplayer is a thing, if you want. You certainly can play career mode, but the appeal is clearly to build and put your creations to the test before uploading them to the workshop.
