Knights Field series. I never could get into them back in the day, but I've been on a retro kick with my Anbernic and got sucked into them. Ended up putting 20 hours so far into the English translation of the first Japanese KF.

Also, Vagrant Story. Pretty much same scenario where I rented it back in the day and bounced off the combat for not making any sense to me. Tried it recently and really dig it. The combat system is really quite clever once you understand it.

Mass Effect. Played the first one and couldn't get off Eden Prime cause of the shitty starting rifle and the OG game's idea of weapon stability.

Played Mass Effect 2 years later and beat it in a week, just absolutely loved the whole thing. Went back and played the first one after that to get the whole story. Then waited for ME3 to come out.

I still hate the way weapons work in the original ME1 but I pushed through, not surprised it turned people off of the game though.

I have two very different kinds of games I did this with.

The first was Undertale, didn't really get into it at first and stopped playing it around half way through. However after I watched someone else beat the game I got a lot more into it and finally beat all the main endings. Really liked the story and it quickly became one of my favorites after that.

The other is the Crusader Kings games. I got one of them when I was pretty young through a humble bundle and did not understand how it worked at all. Then near the end of highschool I finally tried them again along with playing Stellaris and thats when I was finally able to figure out how to play them and got super into a lot of Paradox's games.

Mount & Blade

There's a cheat that puts the game into slowmo, and it was the first game that pretty much let you dive into an army of soldiers and take them all down with melee combat. It was glorious.

Plus there was a cheat that would let you teleport, so sometimes your enemies would go rally an army against you, and you could literally teleport behind them and take them on the hills.

Glorious game.

Witcher 3

Was overwhelmed with most of the game mechanics.

Horizon Zero Dawn. The first time I played it I could not get into the tutorial, just felt so bland. Then years later I tried it again, pushed through the tutorial, and it's now my all time favorite video game series.

Pokémon Unite

I tried it early on but I felt it lacked the maturity and depth of playing a more serious and in-depth MOBA like League of Legends. I played a lot of Pokémon games throughout the years but it just paled compared to how fulfilling the long-form games and lore of Leagues went.

Turns out I’m a dad now and these shorter, punchier games are both perfect for me and somehow more fulfilling. On top of that they added complexity with Boost Medallions without breaking the game with them. It makes the setup more cerebral because you lose stats as well as gain.

The Witcher 2. I died so many goddamn times in the intro scene, rage quit, came back years later and thoroughly enjoyed it.

Thief: The Dark Project

My brother had acquired a pirated copy for me. But the videos and dialogues had been stripped out to save space. He was gushing about how your footsteps would make different sounds on different floor types, but I already knew that from Jedi Knight. So I really didn't get what the fuzz was about.

Don't know how much time later I got a full copy and completely fell in love. It's one of my all time favourite games. The atmosphere is the best. And the different footstep sounds actually serve a gameplay purpose.
