The First 2 were amazing. The only thing that was lacking was graphics, but storyline well made up for that.
I liked them as they were, and I like the character heads better than any face in Fallout 3 or NV.
(The shame is, that these days they could have those heads be their realtime regular faces in the game.)
Whats wrong with the graphics? I thought the Art Design was really good, almost comic booky, and that aesthetic adds a lot to the atmosphere.
IMO they depict a decent and informative scene at 90'. The game sprites of the characters are all really good archetypes, and IMO very good art given the pixel and color restriction placed on the artists.
