I encountered that crazy physics problem both solo and in co-op with 1 other person so it's not MP related. Also in SP, I had a truck with a trailer just not want to move forward (down a cave yes. Up it, no and the slope was gradual). We'll see how long the reviews stay positive. I also encountered another bug: get a shuttle and spaceship built and you can land one inside the other. I've also had crazy physics with a large solar panel, disconnecting tethers to said panel, and in co-op had a spacecraft disappear into space on the person I was playing with.
Interesting. I wasn't aware that those physics bugs existed in SP as well. My SP game has been going off pretty much without a hitch. It's the MP one I've got going on with some friends that can at the drop of a hat become like the twilight zone!
Of course you can have fun even with the bugs.......for instance.....
I have now rescued both my truck and my rover (rover is now affectionately named 'STRATO-rover' since it LOVES to hang out in the stratosphere!!) several times. All using some pretty fancy 'engineering' ie. building 'space-scaffolding' (using the terraform tool) by terrain-shaping/creating and running MILES..........and I mean MILES of tethers to keep breathing and syphon power from one of the bases.
I swear I've explored more.......and run more tethers all over the terran planet thanks to 'engineering-around-bugs'.......than just even for the sake of 'playing' the game. It still being an ALPHA makes that an OK thing to do......imo.
All in all, I hope this game doesn't remain a truck-load of stratospheric potential but actually ends up properly finished.
Here's to a fantastic start!
