I won't believe any of that until I can actually play it.
It looks suspiciously scripted in some parts.
Everything with a pinch of salt of course at moment until the public release. However according to announcements at the show, most features/areas shown should be available in 3.0 to be released in next couple of months then with frequent content updates to update & add systems.
Then they are moving to quarterly updates from then on instead of updates based on blockers & "when they are ready" fixes.
I spotted a few glitches & issues in the footage here and there (AI standing on benches was main one) and most was raw footage from systems that are still very much work in progress as some have only recently been implemented & not yet ready for public release. The AI system for example has only recently been put in place & will be updated by time of public release (outside of Evocati) within months. I'm interested to see the fauna updates & more colourful lush planets too.
Squadron 42 will be shown off in Dec too finally in its own separate showcase. I would imagine it will still be a couple of years away from full release (Beta end of next year) of online Star Citizen with Squadron 42 to be released mid/late 2018.
Their YouTube channel has loads of 40+min videos showing everything in far more detail than that one video. There was over 7 hours of footage to get through. I quite like watching the bugsmashers videos as they are quite interesting to see the process of dealing with bug reports & the devs walking you through how they fix certain bugs. The animation system was the most impressive new video I have to say though...
All in all no matter what, I'm impressed with the systems they have & their ideas and this gives me hope of the scale of what games could be in the future. I won't be putting down any money until release & I don't mind how long it takes them to get to their goal.
