Bro, I don't entirely disagree with this sentiment but I would argue that open source isn't always great despite how anyone feels about it. Unless you are categorizing open source with indie games. In my experience open source games are typically not great in the slightest at all. However, I agree with this sentiment if open source is being referenced to indie games. A game doesn't really have to be FOSS to be great.
The issue isn't really games like Assassin's Creed either the issue is big companies. Assassin's Creed isn't my game but I hear the newer ones are good. Assassin's Creed wouldn't need to be open source to be good.
I love my Armored Core and Baldur's Gate for obvious reasons, but there are some absolute gems in the FOSS scene too (And I'm not even gonna mention all the indie stuff) like Mindustry, Xonotic, Zero-K, Shattered Pixel Dungeon, Unciv just off the top of my head.
Even though alot of them are just rehash of older titles or abandoned projects but even those are improved far beyond their original iteration.
What I actually find problematic with FOSS games are stuff like low player count leading to a poor multiplayer experience and most games being very old school-ish (Xonotic is literally an arena shooter made on basically the Quake engine 🤷)
