yes, went back and beat both after i had played 3 and NV. had a blast. they were awesome games, especially 2, which i waffle back and forth between with NV on which is my favorite game in the franchise.
i like how both 2 and NV took all of the things that were great about 1 and 3 respectively and improved and expanded upon them.
It don't matter. None of this matters.
