Good point, I partly agree. To me it's not the "mind/brain/life taken over by an external force / entity that makes you more of an NPC or supportive character yourself"-aspect; to me it's all about the endings, that pull everything down. Because no matter what you (as V) do: in the end you lose everything. You can only choose between loosing before during or after the finale, and whom you pull down with you.The story was pretty good. But no fun.
Problem is during gameplay I felt like I wasn't protagonist.
Playing a supporting role is not very fun.
There should be one ending, that makes you end up in the streets again, where you lost everything you have collected throughout the game, but you got rid of the chip, and have the possibility to maybe move town and start all over again.
Or at least the option to get rid of the chip before leaving town with the Aldecaldos.
Any option that bases on a perspective. A rewarding ending.
Because as it is absolutely nothing in this story matters in the end, and that's why I love everything about this game (the pulse of night city, the visuals, most of the game mechanics, the sounds), but hate the depressing ending and don't want to re-play it.
