Neither of these are popular enough to be on the scale of LoTR, but in terms of atmosphere and detail:
Hollow Knight - my absolute favorite thing about it is each NPC has its own voiced language recorded, babbling in the background as you read the dialogue.
Subnautica (the first one) - shitting myself with each new experience is something I’ll always cherish. Highly recommend just playing without looking into the gameplay or plot. Has elements of exploring, resource gathering, base building, psychological horror (not graphic, just tense scenarios), sneaking.
Definitely don’t put grease or oil down the drain if it is solid at room temperature. Even oil that’s liquid at room temperature is bad for sewage systems - they combine with non-biodegradable sewage waste such as wet-wipes (Don’t flush wet wipes down the toilet. Put them in the trash.) and turn into rocks that narrow and block the sewage pipes. See wiki on Fatbergs https://en.m.wikipedia.org/wiki/Fatberg
