Fallout 4 plays the best of the fallout games, so it is a great basis to build on, which I think London does successfully. It is content rich, well written, and despite Urban Sprawl and accompanying countryside being well trodden ground for Fallout (as both Fallout 3 and 4 is like that), Post-War London is a well realized location. The game does have that undeniable "Mod Feel", between the varying quality of the acting and recording (though I can't think of anything bad, with major characters all being very well done), a few places where even pretty natural behavior isn't accounted for, and the large number of real world weapons modelled. My biggest complaint honestly is that, unlike 4 or New Vegas, none of the endgame faction are represented before the mission right before you open up joining them (excepting the faction of the main antagonist, which is purposefully mysterious), rather than introducing them early so you can vibe check them. Also unlike 4 and NV, rather than getting a small number of missions for each faction before you get a warning that you will be locked into their questline until the end, here in London once you go sign up for a faction and get their proper quest, you are locked in, with said antagonist faction giving you 1-2 (i forget precisely) before it locks out the rest. On a personal note, i am saddened by the lack of energy weapons with their only really being 2, and one unique ballistic weapon that has been converted to energy.
