This mod contains a new settlement, several NPCs, a new side quest, and a new unmarked quest.
2023 review: So, I should start this time my thoughts with telling you right away that other sml3816 quest mod called "Ghoul King" is way better than Finchley Heights, sadly. And if you need proper new dungeon type quest or something similar to creator's mentioned mod, you'll be disappointed.
By this I don't mean that it's absolutely worthless job, no way. Finchley Heights as a new "town/building" mod is bearable. Many dialogues with its residents, actually decently crafted interiors of every house, few vendors and place just feels like some variation of Grayditch before ants invasion (from vanilla game).
But new town actually lacks more gameplay content. You can talk with people (another plus for optional dialogue lines for every karma character, it's really necessary and my gratitude for that), do one little unmarked quest (after which you'll recieve option to do repeatable fetch quest) and main quest in, again, fetch style with two different endings. And fetch quests can also be pretty good, if creator would provide new gear, enemies or various new locations to "clean up" for player. And not this time, because two quests from this mod can be completed in 10-15 minutes, without any new cells.
When exploring Finchley Heights, this project really reminded me about other new quest/town mod which I translated some time ago. Of course, I'm talking about Mounton and that new town actually has one main questline (way longer than Finchley Heights) and 4 side quests with at least two endings for all of them. I don't want to put anyone down or advertise Mounton, sml3816's project isn't that bad. It has "solid ground" (or foundation, if you want to call it more metaphorically), but now it needs love, passion and additional content to make this place more actually "playable" from gameplay perspective. And, by looking through permission rules that author chose in the description page, it's really sad that no one can create proper enhancement addons for this mod, without somehow reaching original author.
I would really like to revive this project on my own, but as for right now and in this state - Finchley Heights is well-crafted, good looking, but half-empty demo version of (potentially) great new town mod. And in no way, as stated by some users in this section, it's underrated. No, it's abandoned creative piece of land with big potential for new stories and adventures, but not underrated hidden gem.
As for bugs: everything worked as intended, no confilcts with popular quests/locations mods (except, already mentioned by author in the description, Evening with Mr. Manchester). Although, yes, I can agree with RexBellator about bad enemy spawn right near the entrance of town which author didn't move away for some reason. At the time when I reached Finchley Heights, 3 inhabitants were already killed by vanilla Big Radscorpions. But "resurrect" command helped, as always.
Anyway, should you try this mod in 2023? With great sadness, but honest opinion - if you need proper new town with various main and side quests (and different endings), but with the same quality of interiors as in Finchley Heights, it would be better to play Mounton mod. Also I really suggest to play Ghoul King by sml3816, because this mod is good and actually brings interesting side quest with new dungeon. But Finchley Heights will remain another "good idea/potential, poor/weak execution" type of mod in Fallout 3 modding scene until someone will get permissions to revive this little place of opportunities in the Wasteland.
Still support and gratitude from me for good idea.
