FO:3 and FO:NV were both amazing experiences. It was also the first time I've found myself considerably at odds with an RPS WIT. NV does have better characterization by far, but not *so* far that the flaws of the engine and scripting issues don't get annoying after a while. Mods go a very very long way toward making both games superb, but less so for NV as it has a bit more out of the box having learned from the failures of FO:3. NV's DLC is also worth mentioning because (even with the arguable weapons pack) every single one was a solid value that adds a great deal to he game. That wasn't true for FO:3, Oblivion, or many other AAA dlc's of the same genre.
