They changed the overall game design in Assassin’s Creed Origins, but not out of goodness of their hearts. The game’s new direction was more compatible with microtransactions.
Was it? The primary thing they’re selling through MTX is player and weapon “skins”, which were already a thing in the past games (they didn’t sell them, IIRC, but realistically they could’ve). I guess the booster packs and stuff like that wouldn’t really work without the RPG leveling, although I question how profitable those really are.
