You must have not been following the game then, Gamescom 2015 presentation showed for the first time:
- Double Precision 64bit map tech in place = Large World
- Multiple Physics Grids = Multicrew Ships interaction
- EVA
The foundation for the later patch in 2.0 (November). People now take those for granted but what we got was even better.
Besides what was already shown in gamescom:
- Double Precision 64bit map tech in place = Large World
- Multiple Physics Grids = Multicrew Ships interaction
- EVA
We got additional Missions/Quests/PVE and FPS to boot.
As I said several times, expect planetary landing showcase, even bigger world map stuff (new additions to the Stanton System), new pirate base (gold horizon) / Asteroid base (nyx) in Gamescom (August) & CitizenCom (October) and then in November/December the roll out to the public build just like the year before, same modus operandi as last year.
And I'm not even accounting new ships they will add to flight and hangar ready (Reliant, Herald, Caterpillar, etc)
There hasn't been a show that Star Citizen didn't made an impression, being it on it's backers or in the gaming press, this Gamescom will be no different. Prepare to be mind-blown.
