You know they really could have gone with having the WoL be fully capable of speech so that the only thing they controlled was their name. LaTale is an mmo where you are playing an adventurer who has full lines of dialogue and barely any meaningful choices (only one I know of is after you get the third job and go to an npc and answer right, haven't dared to answer wrong yet lol) from start to whatever is the current finish. I'm sure they could have had voice acting and swapped out pronouns and race for when they needed to address the WoL. If not that, then something like in Baten Kaitos where you are the Guardian Spirit and the correct choices will lead to getting better cards and finishers in battle while your partner does all the talking. The problem is they are creating a character over an mmo one where these two were established from the start, but with the former having different stories attached to their creation (I think, it's been a while since I started on anything that wasn't the starting four, I know Card Master had one and so did Demigod) and the latter remaining the same. In that case they should have went with what LaTale did, except not die twice and be on it's deathbed a third time over fourteen friggin years because Actoz doesn't know what they're doing (but the gameplay is far superior to XIV in the sense that you have almost full mobility, it's like an old school Sega Genesis hack and slash but you can fly across the screen with certain skill combos on several if not all the classes).

A less wordy example would be FFX's Tidus but with significantly less WHEEZE-tier voice acting. Probably should have just said that lol.
