Hiya,
Im sorry but i can't answer that. Inside my head there is a pretty good wikipedia for rides and themes and shops but i don't know anything about Blueprints. All I know is that the console editions come with a couple more blueprints then the pc versions did back in the day. So yes, there is a good chance your nephew has a couple more blueprints in his game then you have in your pc version.
But i can't stress enough that basically there is no difference besides you have to subscribe them from the workshop or build them yourself. It should not make a difference inside/outside sandbox because if the blueprint holds a piece that is not available in a certain scenario, you won't be able to build the blueprint anyway as it has "un-researched parts"
Thanks again
I appreciate it a lot. my referral to sandbox was that i do not need to worry about economy, so if i plant a huge restaurant instead of a small shop, it dosnt matter there ;PIll subscribe to workshop. Thank you for your time!
Kind regards
