If they don’t sell the game but a long term rental license, then they should not say “we’ve sold 1234557890 copies of <game>”.

Usually the arguments I saw in favour of decriminalisation instead of legalisation are:

1. Taxes, nobody wants to pay taxes
2. The introduction of licenses, regulations, bureaucracy and any other burden that having a business or being an independent contractor requires.
3. The government knowing perfectly who is a sex worker in the case that it decides to ban it again and go against them.

I’m in favour of legalisation and proper regulations (I think in professional porn industry actors/actresses are required to be tested periodically), however I also worry about the point 3.

Not the one you replied to.

Decriminalise (the proper word) is to stop prosecuting people, it still illegal but not criminal charges would be presented to people breaking the law, maybe civil fines at most.

Basically, the system turns a blind eye on the topic.

Legalise is to change the laws to not only no longer to be a crime, but also recognises that is legal to do it. Usually it involves regulations on the topic.

Take alcohol for example, let’s imagine if you have a store that sells alcohol and the police pays you a visit.

Scenario where is illegal to sell alcohol: The police arrests you and you could face prison.

Same scenario but selling alcohol is decriminalised: The police ignores the alcohol.

Same scenario with being legal to sell alcohol: Police asks four your license, checks that the bottles came through the proper channels (no counterfeit and product of dudose procedence that can pose a health risk) and questions people about if you sell to minors.

People are usually in favour of decriminalising prostitution rather than legalisation cause they want to be left alone. Legalisation would make it like any other job, requiring a permit, pay taxes and probably a license, however it would bring the same protections as any other business (for example, a sex workers could call the police without fear in case is assaulted by a client).
