Dragon Age: Origins. Not sure why. I was a big fan of Mass Effect already, and of story heavy RPGs in general, but I stopped this one pretty early on and sat on it for several years. Needless to say, it stuck the second time and now I've played it and the other Dragon Age games multiple times.

Witcher 3

Was overwhelmed with most of the game mechanics.

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.

Dota 2. First time I played it it was not for me, I only played it to hang out with my friends. Many years later I had an itch for it, so I started playing again. And I haven't stopped. It is an excellent game.

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.

Cyberpunk and RDR2 both

Dark Souls, took a partner to get me to give it another shot, I've played all souls games since lmao

Since the Trails series is continuous, it's what I think of with this sort of thing. I bounced off of and had to nibble at Trails in the Sky over a good while until the third game hooked me. I never would have gotten rolling with that series without pandemic lockdowns.

Now, Trails to Azure is firmly in my top 5 games.

Etrian Odyssey

I tried the demo for the fourth one and just didn't really like or get it. A couple years later Atlus announced Persona Q (which has mostly the same gameplay as Etrian Odyssey) so, I decided to give the demo another try and it just clicked this time. I have no idea why I didn't like it the first time around.

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.

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.

I'm currently playing through Shadowrun : Hong Kong and really enjoying it. I'm not sure why I bounced off the first time, I played and enjoyed Shadowrun: Dragonfall and Shadowrun Returns but Hong Kong just did not click with me the first two times I tried
