In more story-focused games well-crafted, well-written companions are nigh-indispensable.
But is Wasteland story focused?
That's my issue with this - it's the standardization of RPGs. Now every RPG has to have BioWare-like companions, be open-world-ish, focus on story, offer morality choices, etc... Even a franchise that was brought back from the dead to deliver "old-school" gameplay is abandoning part of what made it unique to go to the default "modern RPG design sheet".
Where does this stop? Until someone Kickstarts Wizardry 9? Or that too will have UNIQUE and charismatic personal ego-masturbators following you around and sharing their sad childhood stories, because creating your own party is for losers? "Fight alongside (and romance) Werdyna, the goth teenage daughter of Werdna, who seeks to learn the truth about her father..."
And how the hell do you even make "iconic" companions that are customizeable? Either you'll be severely limited, or it will be utterly ridiculous - "Yo, I'mma play KOTOR now and want an all-Jedi party, so I'll just re-spec HK-47 and Ordo as Jedis." or maybe "Edwin and Aeris should both be barbarians for this playthrought!". Sounds really solid and well-thought out.
