I played a LAN game last night for 2.5 hours without a problem (to play lan, use direct connect and enter the server's local ip address). Was really enjoyable, fought off a ghost ship, a Van Nuemmon, colonized a bunch of worlds, built stations, researched, built a trade network, made a new stellar province, assembled defense fleets.
There is so much to do. The game is such an ambitious project. It's a very complex game with the deepest gameplay I've seen in awhile. I'm not surprised there have been bugs.
Kerberos has proven their support for SotS 2. They have been squashing bugs relentlessly since release. They released a free expansion. They just rolled out a weekend patch. These guys have proven they are committed to their game. Buy it and enjoy, if you find a bug, know that it will get squashed.
