Thanks for the detailed answer @ukbajadave!
Yes, I joined this forum three years ago but my real commitment is just starting now
I have a room but not the space yet, Lego/books/boardgames (another hobby) something will stay in the dust.
I like the Space Lego but the old sets are not cheap at all, moreover I'm interested in Ideas, Creator, City, Modular, Castle and Pirates themes as well, too much stuff!
I will try to download Stud.io then, building something with the available bricks is fun but also the projects can be interesting too.
Moreover I'm not sure if to buy sets can be useful but displaying them because the Saturn V is still intact and I don't know if I will ever use it for the bricks
