Exactly, it apply to every product, and SQ42 will be like every other product.
The SC "product" is not reviewed because, as you said, it's still an alpha! It's amazing you don't grasp that when you write it!!!! You don't like it and you desperately want it labeled "ready for review" but no, it's an alpha and it's not ready for review and the press know it.
Don't judge the quality of SQ42 using SC, nobody know the real state of SQ42.
Everyone say Starfield is a direct competitor to SQ42. Just look at how "limited" the pre sales of SF are

... (note : SF is limited at 30fps on console, sure it will be also need a powerfull gaming PC). If SF sells well and hooks a lot of new players to the space game genre, it will also directly benefit SQ42.
You seems also to forget that the marketing team of CIG is good, that they will have a nice budget at the release of SQ42 and that they can use pretty wel known actors to sell the new IP (mark hamill, Gary Oldman, Gillian Anderson, etc).
