The rocky road of my Fallout history...
Wasteland - started it all, still my most influential game of all time.
Fallout - tried and tried with that - found it too testing for my patience. Unforgiving and difficult.
Fallout 2 - never really progressed with it due to me not sticking with the original title.
Fallout 3 - loved that - played it through to completion.
Fallout 3 : New Vegas - was expecting to be drawn in like Fallout 3 - but felt nothing of the sort. Gave up on it quite quickly. Felt more like a patch to
Fallout 3 than a standalone game.
Wasteland 2 - loved it, more so with the revised Director's Cut version. Played it through to completion.
Fallout 4 - initially tried it and liked it. Ran a bit crap on my PC back then, but is silky smooth at the currently. Will pick it back up for sure if there's a next gen update inbound.
Fallout '76 - never tried it (currently free on Amazon Prime Gaming).
Wasteland 3 - started it and liked its vibe. Didn't quite the pull of
Wasteland 2 and I got distracted on other things instead. On that 'one day' list of stuff to finish.
