Yes, it depends on us. Some believe it and choose to seek a high RTP, while others choose to prioritize it and play any game they want. In my experience, a high RTP doesn't guarantee a win, and the same goes for a low RTP.
I've had maximum wins in games with low RTPs, and I know it was pure luck. So, whether you believe it or not isn't the issue. There's something more important than that, in my opinion: setting limits so we can maintain good self-control while gambling.
It’s still better to check the RTP and decide for yourself before playing. It’s not just about loving the game regardless of RTP.. And come on, as gamblers, we only start liking a game when we actually experience winning. And with a higher RTP, your chances of winning slightly improve compared to games with lower RTP. That’s just the logic behind it.
Ensuring a high or low RTP is important, but it shouldn't be your top priority if you already have a favorite slot game. Every time I play at a casino, I always play Sweet Bonanza and Mahjong, as they have long been my favorites. I never really think about RTP. However when I want to switch games, I sometimes check the RTP. The point is for me, there is a difference between favorite slots and non-favorite slots.
