While I was reading about SC over the holiday period I heard about the an engine change, but I'm not at all concerned.
From what I've learned the switch to Lumberyard was a straight forward affair due to its similarity to the previous engine, and there are now a wider range of tools, etc. available for future development, as well as Amazon infrastructure.
Perhaps I'm new enough to following the game, though I've been aware of the title ever since the original fundraiser. My waiting has just begun, and so I've not developed the cynicism or frustrations other may have. Most recently I watched this podcast
which seems to be fairly balanced, the three players involved sharing a balance of enthusiasm and frustration about the pace of development, and what they're able to enjoy right now. Interestingly all three seem to be estimate 3.0 going live around the end of spring.
They also linked this production schedule
, which looks at the current release detailing what features, etc. were ahead, on, or behind schedule (and by how much), and an intended list of stuff for what's coming soonTM
In terms of what I'm looking forward to, I think the recovery/salvage/resourcing gameplay along with hauling and trading looks really good. I like the NPC crew idea too for the larger ships, which kind of reminds me of some ideas from another slow moving kickstarter (which seems to have drifted from its original concept) - The Mandate
I decided to go ahead and register an account, so there's a character waiting with the "Bataav" name, though I've not paid them any money yet for one of the starter packages.
