Just FYI, unless you absolutely need anonymity from ICANN/the country owning the TLD I wouldn't choose Njalla. Legally any domain you purchase is owned by them, that's how they can keep your name from law enforcement requests. However, that also means in any dispute between you and Njalla they can just refuse to service you and keep your domain without recourse.
Normal domain registrars are regulated and if you purchase a domain through them you are its legal owner, if they don't want your service they must still allow you to transfer the domain somewhere else. Any good registrar provides domain WHOIS protection and will only give out your name to legal requests by law enforcement, so I wouldn't worry too much about that.
PowerShell doesn't stop on errors either by default. And of course a significant number of tools you need aren't available in PowerShell, only cover partial functionality or are an exe you need to call so even if it did stop on error, doesn't work for those tools by default.
Any total war game really, you also get the fun of actually commanding an army.
