I have never considered sound and music an important factor when selecting what games to play.
Try
Reactoonz 2 mate, the music and sound effects are so good!
I was pleasantly surprised when I played Hotline 2 the first time exclusively for the soundtrack it featured. Have you ever tried it?
Yes, but I like Hotline 1 better. Also, the music isn't quite my taste.
If we are talking about PC and PlayStation games, I would agree with you. But when it comes to games where I expect to win something, or I wish to win something, I don't really care about the graphics as long as the payouts are decent.
True, RTP for older games are usually higher at ~97% (depend on the provider), and it still has lots of loyal customers. It depends on how high RTP reduction is for newer games, some (or probably the majority, due to slots hype) may still tolerate it for the compensation of nice gameplay.
I personally won't spend much time on old slots, and won't touch slots below 96% RTP. In the end, it's just a game that will make users poor even though the RTP is higher.
I didn't add this option in the poll, but do you like the double or nothing coin toss game that some slots have after each win?
And the wheel of fortune to gamble your free spin. Not my favorite, since my gut cannot take it.
