Hey, grrr ... I used to be an exclusive
Saucify (the software of the casinos you mentioned above) player. They were my "go to" casinos.
For some reason, I quit playing at Saucify casinos and have been an exclusive
WGS player for a while now. My "go to" WGS casino is Intertops. Intertops has their Classic version, which is WGS, but they also have their Red version, which is RTG. Because they share the same wallet, I do play a tiny bit at Red. Intertops was one of my first casinos that I made my very first deposits at over 10 years ago when they were Microgaming. I've stuck with them all these years because #1 I trust them and #2, I have the WGS/RTG versions I can play at with one deposit.
Are the games cooler at WGS/RTG than at Saucify? Some are and some aren't. All I can suggest is that you "play for fun" at Intertops or any other casino, so you can check out the games and see if there are games that are new to you that may be fun.
Hoping to hear from other members as well.
