Or if the gating has a real purpose, then let us know. If there are a lot of things you want to do that require companions to have known each other awhile, so be it. But only 3? That's an awfully, awfully low and lonely number.
But it is exactly the limit for companions in co-op. To keep the game balanced and be able to track and evolve proceedings in greater depth, it makes some sense ( or, at least, it is more manageable ) to impose the same restrictions and conditions of play on SP as on MP.
If it is done in a way that "feels" right in roleplay terms, then I suppose it is acceptable; but it does often feel that the SP mode isn't really that important for BG3, even though there seems to be a body of players for whom SP is the most/only important mode for RPGs.
