#48: Tetris 99
I love Tetris. What makes Tetris 99 especially great is the variety of modes apart from the standard online 99 mode. The team mode is an especially cool idea that doesn't necessarily change how you play, but it's still really interesting.
Then there's the big block DLC stuff like the endless mode, which is basically the original Tetris.
It also just got alot of character, the soundtrack is great and unlocking new designs and icons by finishing the challenges is satisfying.
Even though I'm actually pretty bad at the game I got highly addicted to it and played the crap out of it for over 200 hours, and never won in solo mode (I'm bad).
Now I still come back to every special event to get all special designs. And it never gets less fun, despite me always losing.
Tetris' infinite replayability makes it one of my favorites and this one gives it an extra layer of excitement and challenge.
