Alright, let's just get to the point.
1.
HCR2 (Chinese + Worldwide)
I really like these, not only you have to navigate your way to victory, you also have to do it faster than your opponents!
2.
Bloons TD Battles 2
It's a fun competitive game where you can fight against other people from all over the world!
3.
BTD5 (Mobile)
It's basically Bloons TD Battles 2 but older (yes, it still gets updates), but it has great gameplay!
4.
FR Legends
Bet you didn't expect FR Legends to be here, huh? It's a great drifting game where you can play against bots and even your friends!
Conclusion
You should try all these out! These are all great games!
