Recently, I'd thought about casinos creating a general overview of the list of crypto casinos both from the past and existing and the new ones coming onboard for gamblers to see and develop interest on them, this will help in having a collection of various games and when they have being added to the casino or the general information needed about a particular game, but most importantly gamblers prefers the new coming games having a different dimension of approach in gambling.
This is a very interesting question.
Indeed, you also made me think about how many different games I have seen and how many of them I have played in different time intervals of my life. Of course, progress in this area is quite fast and many games become obsolete or generally forgotten about them when some new games appear, for example, with much more interesting design, beautiful pictures or with expanded functions. But, I think, the generally accepted classifications of gambling may well give an idea of what is happening in this market and what are the approximate trends in its development.
I think that developers of software and design of gambling interfaces are quite smart, literate people who seriously follow what players would like to see in the next updates of well-known and widely used games. So, for example, players may not like the next update, but after trying to play and getting used to the new interface a little, most players will appreciate such recent updates positively. And they will never use outdated versions at all.
Progress in this area of gambling cannot be stopped for anything!
