If I do not have a job whatsoever can I use store.steampowered.com Steam money to purchase most expensive per year Construct 3?
If Yes ^ how do I properly use Steam to install Construct 3 most expensive edition?
With Steam money can I pay for second most expensive per year Construct 3?
If yes ^ how would I use Steam to install Construct 3 second most expensive per year version?
Construct is not on Steam. Unless you mean with money you earned from selling games on steam, in that case that would work of course.
With most expensive Construct 3 per year if I get proper licenses from a company such as Nintendo can I publish a game for free made with Construct 3 to a gaming platform such as Nintendo Switch 2?
Yes but publishing on Consoles is a bit iffy you'll have to hit up one of the 3rd party porting companies (Ratalaika, Penguin Pop, MP2 Games)
Do forum rules permission someone to link to safe to upload stuff websites such as a website that has for a monthly fee of thirty eight dollars the ability for such a person to upload up to 123 Gigabytes of data per downloadable file?
Not sure what you're asking exactly. If it's spam/advertising for the site: no. If you're just linking a file you uploaded for a reason like asking for help on how to fix a bug in Construct: Probably fine.
Do forum rules permit linking to YouTube and similar videos?
Yes, as long as it's relevant I'd say
