goris FTW. kiddies never played FO2...
Took the words out of my mouth.
It's been done. They should come up with something original.
A Super Mutant : FO2, FO3 and New Vegas (nightkin)
A Dog named Dogmeat: FO1, FO2 and FO3
A robot Dog: FO2 and FO New Vegas
A Casidy: FO2 and New Vegas.
A Robot Follower: FO2, FO3 and New Vegas.
A Ghoul: FO3 and New Vegas
I don't see your point... Its been done yes but not over done. I'll agree another Talking deathclaw would be odd for New Vegas.
I forgot Lenny, thanks gabriel77dan.
