Beam.NG would be one just because it covers nearly every driving discipline and the other would probably be Cyberpunk. It’s not even that Cyberpunk is my favorite, but it has so much content in it at this point that it would keep me busy for years.

Probably age of empires and MCC.

DayZ and minesweeper. DayZ has probably the best replayability over any other game I've played. On top of that it's also the game that gives me adrenaline rush like no other game has. DayZ is highly underrated and I highly recommend it in 2024 as it just keeps on giving.

the talos principle 1 and automobilista 2

Terraria and I can't decide between Skyrim, Fallout New Vegas or BG3.

Civ 6 and I'll sell my other slot to the highest bidder.

Slay the Spire. I probably don't need a second.

Team Fortress 2 with either Deathmatch Classic or Ricochet....

Factorio now, and I'll save my second one for Factorio Space Age when it releases.

Path of Exile 1 and 2. Not much would change

Assetto Corsa (assuming mods are included) and Factorio (again, with mods, but to a lesser degree).

Rain World!!!!!
Second place is hard to do though! Oxygen Not Included, I guess?

path of exile

Path of Exile and Rocket League

Some hard choices. I generally like my RTS and FPS games. I play a wide range of games from story driven like the BG series, to yearly play throughs of 93's Doom, to mil sims like arma.

I have a hard time to stick to one game for a long time, so whatever I pick would need to be moddable to bring some variety. I'm imagining maybe a stalker game where there's a wealth of mods, but the world isn't that large. Arma 3 might be nice, you got decent multi-player bots for when the world has moved on, it's very moddable and relatively easy to set up new scenarios for yourself.

I do like my sim racing as well, so asetto corsa would definitely be the main contender there.

If I'd have to pick some games off the top of my head they'd be AoE 2, HL 2, Doom 2, asetto corsa, Ms flight sim (but the servers will die at some point), Arma.

So I'm picturing myself in 40 years time, I've finished building my new rocking chair with the skills I've got from all this free time, I sit down in front of the same computer I have now. I'd say I'm launching up doom to do another play through of Sunlust. Hm or maybe I'll do a bit more work on my at that point 10 year old OpenTTD save. Just something simple that will stand the test (and already has) of time, a game I can fire up and feel just as home in now, as I did last year, and the year before that.

Planescape torment and HoMM III (yes I will take the bundle, thank you)

Satisfactory and Titan Quest

Path of Exile for sure, not sure about the second though. Maybe Dark Souls 2, Elden Ring, or maybe XCom 2.

Factorio and Baldurs Gate 3...

Feels bad leaving off other amazing games though

If we get access too all future updates, Dwarf Fortress is my clear #1 choice.
If we also assume that the game will forever have an active enough userbase that lack of players won't be a detriment: Infinity Wars as my #2.

If we assume no updates, no mods and no guarantee of users: Tales of Maj'Eyal and probably some 4x or grand strategy game, it's a tossup between Civ, Gal Civ, and Endless Legend, maybe even one of the Total Wars.

Dota 2 and Factorio (with mods enabled)

Apex and Rimworld

Would choose those 2 because it would let me kinda bypass that limit
Source Sdk 2013 Multiplayer
S&box

No Man's Sky and Light No Fire

Dirt Rally 2.0 (with my sim rig and VR headset).

I don't need a 2nd game.

If I am honest and base it on my actual play patterns it has to be The Binding of Isaac and Slay the Spire. Or maybe Ascension (digital version of the physical deckbuilder) especially if there is ever more content for it.

Stellaris and Rimworld. Replace Rimworld with Minecraft if including non-Steam games.

That is a hard choice

Monster hunter world and satisfactory
