Thanks for clearing that up. The similarity of the names is very confusing and had me completely fooled.

Answering my own question, here is a link to a blog post from The Document Foundation, https://blog.documentfoundation.org/blog/2026/03/27/odf-is-the-future-ooxml-is-the-past/. The criticism of The Document Foundation centers around the use of Microsoft OOXML format in OnlyOffice instead of the truly open ODF standard in LibreOffice.

That was my first thought too. Apparently Euro-office is based on OnlyOffice. According to Nextcloud and IONOS “Libre Office is 35 years old and no longer the most innovative and fluid”. For more detail: https://www.heise.de/en/news/Microsoft-alternative-Nextcloud-and-Ionos-develop-open-source-Euro-Office-11228123.html. I would like to hear what The Document Foundation thinks about this.

Reading from Wikipedia: Euro-Office is an upcoming open-source office suite and collaborative software platform based on OnlyOffice that provides editors for documents, spreadsheets, presentations, and PDFs. The software includes web-based, desktop, and mobile applications designed for document creation, editing, and collaborative work

I checked the website and you’re right, the game engine is free but the mods require files from the original games.

My current Linux distro (MX) came with gThumb which grew on me over time. It’s simple, fast and covers the basics. Linux only. https://wiki.gnome.org/Apps/Gthumb

I totally agree. On a personal level the least we can do to be helpful by donating e.g to the International Rescue Committee (https://www.rescue.org/) or by letting our voice be heard.
