I wasn't going to berate you or anything. I was genuinely curious.
I am going to be trying out libreoffice and OpenOffice
LibreOffice is great. I use it on my work system at a medium to larger sized company (every single other person uses o365). I haven't heard anyone complain yet about doc comparability and I haven't had any issues myself.
Stay away from OpenOffice. It's practically a dead product. When Oracle bought OpenOffice, the community forked the project which became LibreOffice. LibreOffice is where all the development and community focus and effort has gone since.
OneNote is my second most vital
I don't have any recommendations here. I've never really found a "perfect" solution for this. Currently I use a few different solutions, but it's all centred around markdown, so they're all interchangeable.
OneDrive is probably my most vital.
I personally wouldn't touch OneDrive with a hundred meter pole. MS does so much screwing around with your data that you can never be sure if the data stored is what you uploaded. They've been known to just up and delete files they scan and think is malicious, even if it's a false positive. Then they're known to scan all your documents for everything, including potential passwords, then use those passwords to open password-protected files and then scan them also.
Then there's the situation from a year or so ago where they automatically switched everyone's documents folder to a "cloud first" folder, where they just auto-uploaded everyone's local files, deleted the local copies, and did it all without user consent or even informing users. And this resulted in all kinds of wild crap like people not having access to their documents because they were offline and were expecting local files. Then some people had their metered data connection getting maxed out. While others couldn't even modify their files or even save a file to their "My Documents" folder because the default storage allocation was far less than the total data of their local files. So effectively the data was held for ransom.
it's mostly running dedicated game servers that have no Linux option.
Most newer games that you can run your own dedicated server will almost certainly have a Linux option, which suggests you might taking about older games, in which case something like Lutris (Wine) might be an option.
But are you hosting these game servers on your desktop?
If I remember correctly, Only Office uses LibreOffice as its core and then adds or changes default stuff. I might be wrong about that. But ultimately I hear positive things about Only Office.
Sounds like a perfect situation for loading something like Proxmox and then visualizing the Windows Server 2016 instance. You would basically have the exact same functionality but with way more options like cloning and backing up the server.
No worries at all. I think the automatic defensiveness from Linux people comes from old misconceptions being repeated often. Or sometimes it comes from how something is read and interpreted. Someone might say "I can't switch because I need XYZ", to which a very literal response is "you can use ABC which does the same thing, so you can switch". When what the first person meant is "I can't switch because I prefer XYZ", which is a completely valid reason.
