I’m not sure if there’s any soulslike other than Lies of P that has a companion in it that accompanies you throughout your journey through the game. And many people didn’t enjoy Gemini because of his quippy nature and retelling of main plot points when they happen.
Are you among those people who did not like Gemini? If yes, why and how could Round 8 have made him more to your liking?
And would you be opposed to an NPC follower that is your constant companion? Think, Solaire went along with you the entire game and helped in battle. Would you enjoy that?
I don’t know, seems like a thing that’s hard to get right. A Marvel-quip like character would probably take me right out of the usually dark atmosphere of souls likes. Personally, I wouldn’t like a permanent companion that I can’t turn off. I think the Elden Ring system does it well, with optional summons (either spirit ashes, or the NPC summons for fights like Radahn).
