What game gives you the most warm feeling replaying it?

I had a look at my top 50 and oddly, for me it is Bloodborne. Something about that world is so fucked up that I feel insulated, warm and cosy like when listening to a thunderstorm outside wraped up in bed but it's more than that, loads of small details right down to the sound effects or the manner in which the NPCs speak and the soft echoing of it all just hits right and has an ASMR effect on me, there's nostalgia tied to it for sure but it's not all nostalgia, it's the devs actual hardwork. 

As a huge Nintendo fan, this sensation of warm comes with Until Dawn (2015), I love everything about that game, the dark atmosphere, the blue filter and the French dub. It reminds me of the prime of French YouTube when every YouTubers were playing that game. I truly like Until Dawn. (I love Emily)

Mario Kart 8 is in second place and ACNH in 3rd place.

Age of Empires 3. From the historical colonial setting, gorgeous graphics, superb music, maps, card system, and distinctly unique civs, AoE 3 is my go to relaxation game that still gives that warm feeling while playing. Even after who knows how many hundreds of hours over the years.

Biggest honorable mentions would be Halo: Combat Evolved, Jet Set Radio Future, and Civilization 3.

Probably "the long dark" for me

Sometimes I'll go to Pilgrim mode, gather all the items I'll ever need, then just sit in the watchtower and listen to the sounds of the blizzard

Oh man! This too. Apart from the French dub part I felt so warm paying that game, even the looming monster threat made it feel more...Christmasy. lmao.

I really expected people to be commenting Kirbys yarn world or something, glad to know I'm not the only one who has what would seem the inverse of warm and fuzzy that produces that feeling. 

Warmest? Maybe if I could run Super Mario Odyssey natively on my N64...that would def generate some heat.

To answer the OP seriously: I have absolutely no clue what "warmest" means here Lol, but ig maybe any Mario game. Infinitely replayable, never lose their fun! SMSunshine, SMOdyssey, SM64, and SMGalaxy are def my favorites.

ICO. It's not only an amazing game, I first played it together with my girlfriend, now wife, who was visiting for a few weeks at the time. It's also the first game I bought when I moved to Canada where we finished the game. (Back in the old days where PAL version doesn't work in NTSC lala land)

Warm and fuzzy. Cozy. Safe vibes. Anything in that window from that feeling when you're warm in bed and there's a thunder storm ranging outside to working a day of hard labour and you shower, sit down in front of an open fire and melt in a hypogogic opiate like state. That kind of warmth, it could be triggered by nostalgia or the thought of someone or some place or a memory but in this case a game or a games world and atmosphere. I understand that Bloodborne is an odd choice and it gives mixed messaging but I'm the odd ball that if given a choice of somewhere to be comfortable between a cusy luxury hotel suite or an open air factory working metal with an industrial heater on a cold day, I'd choose the latter. 

If I had an RTX 4090, it would probably be Cities: Skylines II, because I've heard that combo can really warm up the room.

More seriously though, I don't generally get that feeling. But last time I played Wolfenstein: Enemy Territory, I felt filled with joy, because the game was even better than I remembered. It's almost sad how much other stuff, including other games, there is, and it's also a pity the game's community is quite small already. I don't actually even know how small it is, since it's maybe a couple of years since I last played it, but obviously an online multiplayer game that's almost 22 years old isn't likely to have that many players.
