That actually does describe the first two Fallout games pretty well. There's a clear progression from small communities barely scraping by in the original game, to development of a functioning society in Fallout 2 that even has utilities and paved roads in some towns. New Vegas kind of continues this idea, although since they're stuck using Fallout 3 assets, everything still has a rundown look to it that somewhat clashes with what's happening in the writing.

I didn't have a great experience with it. Many of the Galaxy Achievements for that game are broken for me, and it doesn't have any NG+ mode, even though it desperately needs one, and the lack any NG+ mode makes acquiring much of the stuff in the game become mostly pointless and also gives it no replayability.

I wouldn't say it's a bad game, but it's not great or anything IMO; it's quite average.

It is worth the $4.99 USD or $3.99 USD price it goes on sale for, though.

I really wish I started a Whining About Achievements counter for you way back when, sort of like Civvie 11's Sewer Count gag. Now there's way to check how high it should be, and starting from 1 is not really an option (though it would climb fast).

No it does not. It's plenty long enough for a single playthrough and doesn't need to be artificially extended. It's 100% fine to play a game and then be finished. Blah blah blah, nobody cares.

Get out of here, Stalker! :D

Yeah, and Fallout 76 & 4 both look like they were hit by a landfill, but that might have to do with Bethesda.
