Actually I've played them all.You've never played Risen 2/3 or Elex? You most certainly have actual companions. You're just limited to bringing only 1 at a time. The difference between Greedfall and those games is just 1 more active companion.
More importantly though, you can't control the companions in Greedfall. They're AI companions like in PB's games. You can't even adjust their behavior in combat. To me, that's a very significant difference from Bioware's games.
And while you're technically correct (which of course is the best kind of correct) to me these games feel different. To me PB games it feels like having a follower like in the Bethesda games. In the ME/DA franchise and imho also in Spiders games having an party of deep companions is more emphasized.
I can understand that the possibility to control the characters in combat is important to most of the gamers. To me it's not that important.
