Picked it up with high hopes, but it was a huge crash and burn! ABORT ABORT ABORT! Devs simply abandoned it without a single update... If you want a good Apollo sim pick up Reentry. (Covers Project Mercury-Apollo) That is in early access as of 12/22/19, but they are actually doing something with it. Even has a training section that helps you learn the game. If anything changes or the Devs follow through with the game I will revisit it at a later point. Otherwise my neg review stands as is.
