After the favorite http://www.gamesas.com/topic/1499890-ranking-the-main-antagonists/ to fight agains't, here are the favorites companions you love to have around.

I made subcategories as they are a lot in the series.

Amongs the normies, i think Myron will remain one of the favorite characters of the series.

His dialogs, including the ones with the Jet, are priceless. The only problem is that you can't avoid his post-end death.

Otherwise, i have to give a point for Vic and the FoNV companions (Cass/Veronica/Boone/Gannon)

Amongs the not normies anymore, Marcus is the man.

One of my favorite characters of the franchise, he is the guy who will make sure Super-mutants will get the civil rights they deserve.

I like the guy's personnality, but also the fact he actually get result in making normies/ghouls/SM live together, without ignoring the Master principles.

Otherwhise, let say Raul Tejada is the very definition of a ghoul, IMO. A very old man that seen a lot and wait for his final days, unfazed.

Amongs robots & animals i would say Goris, K-9 & Skynet because of the interactions before your recruit them, but they don't stay interesting afterward. And i rather have someone to talk with during the road.

Amongs others, the mysterious stranger have a soft spot.

If i had to rank the average quality of the companions of a specific episode, i would say FoNV quite easily.

There are great companions in other games, but FoNV is the only game in which you could tell all the companions (except Rex) have depth, interesting traits, and a proper involvement into the plot.
