From what I was told and saw, they said it would be available for cross platform for everyone but I'm not to certain on that anymore and have no idea how ubisoft players can join over people on staida and consoles. The inviting menu seems really weird and only seems to work for the platform your on but idk.
The real reason why Far Cry 6 isn’t Cross-Platform. This isn’t unique to Far Cry; there are a lot of new AAA titles that were released this year without the cross-platform feature enabled. This is absolutely unacceptable to the consumer as you pay the total price. If you’re not able to enjoy the full extent of the game, what’s the point? The reasons behind Far Cry 6’s lack of cross-platform support can be multifold. Firstly, there might be technical constraints related to maintaining gameplay stability across various platforms. Secondly, strategic decisions by Ubisoft, the game’s developers, may be rooted in wanting to maintain a particular kind of gaming experience. Py7pa.
