I put in about 5 hours as soon as the game dropped. One thing you should remember is that there are very few places where you can call your ship to your location. Wandering off in hopes of calling your ship to you is going to be a bad idea.
The life we live is not what matters, what matters is the life we leave behind for others.
I'm stranded right now as well. Bought a new ship after putting my warp fuel in the other ship. I am now stuck with no way to warp out of the system I'm in. Several hours later and I still can't find Warp fuel or Antimatter. Starting to think it's not possible. What ever you do don't buy a new ship before leaving your first solar system. I had 20 suit slots before I found Antimater but I found it Wednsday morning 2nd ship I checked.
