Enough said.
But I'll go on; the first fallout titles far surpass fallout 3 in several aspects. While a great game that i love as well, no-matter how you put it, fallout 3 is a shooter. But the original fallouts are about the story, the role-playing, the jokes, and usually not-so-subtle references to various things like pop culture, did i mention the story? Alltogether an excellent game, even with all of its bugs and faults. Definitely a must play.
