Patient Gamers

Rimworld and Skyrim.

Skyrim, same reason as everyone, I've finished most guilds though (yeah, not you, Companions).

Rimworld I just can't be arsed to work towards any of the endings, playing thematic colonies with mods is where it's at for me.

Skyrim for the same reasons.

Satisfactory 1200+ hours, and I usually end up rethinking my setup around the time I get to Aluminum production and never stay to finish things. I much prefer the beginning and middle of the game. I'm weird, though, I do the one big base thing.

Quake I have no way knowing how many hours I played LAN Quake after work with coworkers. Started with the alpha release. Eventually I did Quake World. I've sunk a lot of hours into the single player game, too, but not nearly as many.

BotW for me too, and still is

Until last week it was BotW. Like my switch I bought it on the release day and had a blast. But somehow I never finished it, there were always some "only this one thing before I go beat the boss". It took TotK to finally push me to finish it.

My second big game is Space Engineers. I currently sitting at around 2500h and still having fun, still having ideas. I'm just to easily entertained by "space ship go boom" But technically one can't even finish the game, because of it's sandbox nature.

Valheim. There is so much to do, explore and discover! I play VH either with friends or solo. We've never finished all bosses yet and are currently less active, but we often get very active in bursts of time. I can get lost for HOURS in this game, completely forgetting the time and world around me. Then I notice I've played for 6 hours straight and mostly gathered some wood and improved my house a bit. I never gets boring though.

Don't Starve. I've spend a lot of time in this game and I think I've not even seen a quarter of all the content. I've never even defeated a boss.

Guild Wars 2. Granted it doesn't really have a "finish" but that doesn't stop be trying to complete more and more of it.

Magic The Gathering. From the original mtg (with Shandelaar), to manalink3, and forge. Not sure if the game can easily be 'finished' tho, but it sticks..

Another World. Since it was released I keep coming back to it. Next time I'll finish it!

Probably Europa Universalis 4. I've played dozens of campaigns, and clocked in hundreds of hours (>850), and I have yet to make it more than 2/3 of the way through the campaign time. I usually have a specific win condition I'm interested in (e.g. an achievement, or cool scenario), and once I hit it, I don't bother continuing the campaign.

Other than that, I tend to bail on most RPGs around 50 hours in, so I've never finished any Elder Scrolls, Final Fantasy, etc despite starting numerous times. I feel like I bail when I get too powerful, need to grind because I'm not powerful enough, the story drags and I lose track of the main story line. I still keep starting them, but I almost never finish them.

Does EVE online count? 1k+ hours, only dipped my toes into null sec a few times. Mostly spent in low sec blowing up expensive things.

I've been trying to beat XCom 2 for years but I always end up ragequitting when I lose three guys who miss multiple 90% shots in a row, while behind high cover.

I think most new games have a modified "perceived chance to hit" that makes an XCom 90 a 70 or something.
