Really? KSP2 is not being made by Squad. Squad got bought by Take-Two and Take-Two is having a different studio build the game... or was until they cancelled the contract and poached most that studio's talent. This is a project that seems like it has a high likelihood of failing to capture what made the original one great. I'd wait to see some demos and lets-plays before putting your money down
It looks like Squad did get re-involved in KSP2 once they closed out development of KSP with v1.12
I'm not saying people shouldn't check out KSP2 and I have high hopes it will be a worthy sequel. It just isn't the sequel I would call out as a specific example of a safe one to pre-order.
