JEMC, if you don't like ES games (I don't like them either too much, apart from Morrowind and somewhat Daggerfall)...yeah, FO3 and FO:NV are more or less ES with guns. But, I can't say whether you'd like them or not, there are plenty of folks out there that like ES and don't like FO3/NV/4 and vice versa.
If you really want to play Fallout, pick FO1/2, if you're not too picky about outdated visuals - I think they are dirt cheap on Steam.
