Are there any other games as rewarding as League? PLEASE HELP FIND LEAGUE REPLACEMENT GAME!

I got gold 5 this season and am now bored with league. I realize that I'm not good at the game and am not getting better and I don't get excited to play.

What I like about league is this: Super high upside - when you win a ranked game in a series or something like that, it feels incredible / if you have really close games that you win. I've honestly never played a game that made me feel so great. -This is because it is VERY challenging and you feel proud when you make cool plays -The ranked system for whatever reason makes me feel like winning and growing in rank is worth it

I also only have 1 year to play the game before I go to med-school.

I liked dark souls because: it was challenging, you felt good when u played well and won, and progressing to see more of the beautiful game made it feel worth it to pour time into learning the game.

Is there any other game that fits those qualifications?

No turnbased games No streetfighter type games No sports games Yes maybe to 1st person shooters (I love BFBC2) Yes maybe to RPGs but can't be super super ez and forgiving like lots of them. No it can't be Dota 2 or something that requires another thousands or 2 thousand hours of time to get somewhat mediocre at. Yes it must have some aspect of physical ability, handeye cordination, skill, etc., not something that only requires insane memorization of builds / knowledge of the game

Also, I only have 1 year to play the game before I go to med-school.

Also, am I just too old for video games at this point? Should I just retire from gaming? I'm 22 years old. Thanks!
