Fallout 4. I died easily early on and quit after 20 minutes. A year or so later I picked it back up. 700 hours of gameplay later, I think I've changed my mind.

Bloodborne

Didn't even got to the first boss my first "try" (actually a lot of tries) and shelved it as "I'm not gud enough"

After a colleague nagged me about it again I gave it another try (with a guide this time) and it clicked! 10/10 game of the decade

Witcher 3, is was so bored for the first 30 mins I turned it off. Came back a year later, now got around 300 hours in the game.

Skyrim, thought it was boring at first but started again after a friend got it 1 month after me, im currently on what feels like my hundreth playthrough and it still is my all time favorit

Prey (2017), Monster Hunter, Stalker, Dark Souls. All great games that only show their true self after some time investment. Not too ridiculous time investment apart from Monster Hunter which gets really fun literally only after a few tens of hours, maybe even a hundred. I wish I was kidding.

Hollow Knight for me fits this scenario to a t. I got it as part of a humble bundle, but couldn't get into it for at least a year as the initial part felt really depressing, and didn't at all grab me.

But once I managed to tough it through to greenpath, and started to get some power ups, it finally sunk it's claws into me. I proceeded to nearly 100% the game.

Horizon Zero Dawn

My Summer Car

Witcher 3 Crusader Kings II

Dragon Age

I started with Dragon Age inquisition and I dropped it within the first half an hour. Years later, I started with DAO and now it’s my favourite serie; I replay dao way too much btw

Binding of Isaac, I couldn't handle all the poop and mild horror, but eventually something clicked and now I have 1500 hours combined in both games.

Cyberpunk. Hated all the stuff with Johnny in the beginning. Came back later and actually played through the entire game.

Happened twice, both to my #1 games. Tried Chrono Trigger as a kid and didn't like it, then came back and played it as a young adult and was like... damn... this is an actual treasure.

In 2015 I tried FFXI due to the XIV crossover event, and I could not get past the eccentric and clunky UI and the pacing of the combat. I tried again a couple of years later and committed to finishing all the stories. It became my new #1 and I think genuinely one of the best games ever made, in terms of revealing and pushing the artistic potential of online games, and games in general. Actual masterpiece and a massive innovation, and unlike Chrono Trigger I think the lessons are going to be a lot harder to learn and replicate.

I got Rhythm Heaven Fever for the Wii when it first came out and just couldn't get it. I mean, I understood what I was supposed to be doing, but I could barely pass any of the songs. I figured I just didn't have any rhythm and put it on the shelf.

Fast-forward to 2020 when I was rearranging some stuff and came across Rhythm Heaven Fever again. I hooked my Wii back up for shits and giggles and started playing and was doing great. Either I had magically gained a sense of rhythm or (most likely) the TV I had been playing on when I first got the game had some sort of latency issue.

Now I've gone through all the Rhythm Heaven games, but Fever is still my hands-down favorite. I put a copy on my Steam Deck and sometimes I just load it up and play through some songs when I have a few minutes to kill.

Eve online.

Sekiro. Tried getting into it twice, but couldn't - I always got mentally stuck at Lady Butterfly.

Third time, someone told me that I shouldn't fight her until later, and HOT DAMN is this a good game. I'm still working on the final fight of the normal route, but can't wait to go back and do the other endings!

Hollow Knight.

The first few hours on felt dull. Lots of reviews were praising it and I just didn't get why. Dirtmouth and the Forgotten Crossroads weren't really exhilarating, so I stopped after ~5h.

A couple months later I created a new game slot. My POV shifted by following Cornifer's passion for exploring for exploring's sake, instead of grinding the Geo economy. The soundtrack really enhances the experience and environment of each section. I'm now ~120h in and still unsure if I'm halfway there!

fallout 3. first time i ever played a game like it. stopped playing because the subways scared me and i was out of ammo

Doom Eternal

I played on easy mode, over the course of months slogged my way through over half the game getting wrecked and HATING it. And then one day...

Everything clicked. I got into the Fun Zone or Flow State or whatever it's called. And I have been obsessed ever since. I play at least a few minutes almost every night for years now. I can now comfortably beat it in the hardest difficulty, including the DLC. And it never stops being so much fun and satisfying!

Red​ dead redemption 2

Residentes Evil. The camera fixed angles were confusing and sometimes I got caught between two different angles in a small space to maneuver.

DDR, use to talk mad shit about that game. Can’t remember what happened but I think my uncle bought it for me and then it just clicked. Ended up hanging at the arcade for hours all sweaty getting food court food.

Left4Dead

First time I turned it on I just heard the music and saw the zombies puking and thought it was some kind of horror suspense game and never played it.

I had my GF play it with me since I didn’t want to play horror alone, and we both loved it.

Bloodborne. I gave up on 3 separate times, even after loving previous Dark Souls games. Gave it a 4th and final try, then didn’t stop until I got the platinum trophy. I don’t know that it’s my favorite souls game, but it left me the most satisfied when I finally finished it. Love that game and wish it would get the same remaster treatment that Demon Souls got.

The Division 2

The main campaign story is boring, but end game is tons of fun and customization of gear builds.
