I impulse bought it and must say I am impressed with it so far. However, of course, it has its hitches.
- Physics, mainly for vehicles, can be a bit derpy, but its a Lego game so I forgive them and would not be upset if it stayed this way.
- Camera controls are a bit tedious, and sometimes the camera phases into the terrain.
- While I can nearly max out Minecraft (except antialiasing and anisotropic filtering, of course, which are both at 4x) and hold 200 fps or so, I had to disable FSAA, shadows and texture quality on low, just to hold around 20 fps. The upside: the game was kind enough to tell me it was struggling and to turn the settings down.
Now, it is still impressive.
- Brushes for flattening, building up and removing terrain make terrain editing easy.
- Vehicles, animals, and interactive props.
- Terrain is much more precise due to Legos being smaller than cubic meter blocks.
- Ability to auto build template structures. If you've played Garry's Mod, think duplicator tool, but with a predetermined list of dupes and no ability to save dupes (that is, I haven't found something like this, yet. I'm still playing with it).
I think this game will more coexist than compete with Minecraft. It feels like an improved creative mode, but I don't think I would play this for a survival experience.
