In terms of what is in the game today, you can expect a slightly stripped-down version of stock KSP 1. You will be able to visit all the planets you know in the Kerbol system with many of the same and even some new parts.
Should I get Kerbal Space Program 2 now?
As it is stated above, you are the only one who can make that decision. I personally got the game when it launched last Friday because I’m in it for the long haul. If you’re considering the same thing, then be prepared to accept that there are major bugs that will directly impact gameplay, and know that while Intercept Games will be working to squash as many bugs as they can, it will take time and the first patch fix is slated to come in the next few weeks. It’s not going to be like those AAA games with massive studios behind them getting next-day, or sometimes even same-day, hotfixes for bugs.
If you’re on the fence about whether the game is currently in a state where you want to spend $50 on it, my recommendation is to keep watching Kerbal Space Program content creators, like Scott Manley, to see how the game is progressing and when new features in the roadmap above get added to the game. However, you do risk paying more the longer your wait. While I doubt the price will increase until the roadmap is mostly complete, it is possible it goes up before then.
