Thanks for the offer of the key - I haven't got one by any other means, so am definitely interested.
I'm wary of promising a review (which is why I bowed out to the other guy) due to spare time in the run up to Christmas - I'll try, but can't promise.
As for sucessor to Fallout2 and Jagged Alliance, the .72 Caliber and related games/mods from the Russian scene certainly look interesting.
I still rue the fact that Fall: Last Days of Gaia never saw a release outside of Germany - that looked like an interesting isometric post-apoc game.
The glib answer would be Wasteland 2 Directors Cut. It is probably the closest to Fallout 2 that I've played. The revised battle system with targetable limbs perhaps gives it a bit more tactical depth.
That new Krai Mia game looked interesting - early access on Steam now. But may be too soon to comment.
Whilst not quite the same thing, you could do worse than that new Banner-Saga-Engine game "Bedlam by Skyshine games" aka "Skyshine's Bedlam". It puts me off by using the phrase "roguelike" (I don't like investing a lot of time and then losing all my progress through one dumb click), but I've seen a lot of praise.
An oldie that I personally love - Odium (aka Gorky 17). Group of clueless soldiers go and investage a signal from a russian base (or something) and discover all manner of mutated things to battle in a tactical, turnbased combat system. Bit short, but really fun. But old now. Still have boxed copy.
I'll stop there - hopefully there's one or two ideas there?
(joke) Oh, wait, what about Fallout 3 and JA:Flashback/Reloaded/Retailed/Flogged-to-death? Not to mention Fallout Tactics…
