So I loaded up the new demo since I haven't seen anyone give any reports on what features are there/not there. Here's what I found: In the VAB, there are 26 parts, ranging from SRBs to science parts. The career tech tree is smaller to fit the 26 parts. There is only Kerbin, the Mun, and Minmis, interestingly the ore database is there, and a quick look at the game files shows that ore mechanics are completely functional, but no parts to mine it. The science archives still expects you to reach all planets (which don't exist)? All 3 tiers of all buildings in, but the SPH and runway are not available. The admin building has strategies, the Astro complex can hire kerbals, the mission control works, and even the flag pole works. All with complete interiors and exteriors. The 1.0.0 aero is used since it was not updated to 1.0.2. Science mechanics are also in, along with rep and money.
