Hello,
I personally agree that some kind of sounds redesign wouldn't be bad, and we shouldn't connect this to RS games at all, as it's a very good topic on its own.
For instance, probably my major annoyance regarding sounds is the same sound for PM and invitations, as they are in fact different enough to receive their own sounds.
However, this was discussed in the past and the idea was never refused, it was just not a high priority item. I suspect it will be done at some point.
Anyway, in my view, RS Games has a completely different style. Whoever likes that can feel free to enjoy it over there, but I find their sounds long, intrusive, and simply put, annoying.
In a card, board or dice game, sounds are supposed to be the background, a nice cosmetic item to appreciate, but not something that would play for 3 turns even though the sound already became irrelevant a long time ago. I'm not even joking when I say that in RSG, if I finish a round of Uno, I can't even hear what is happening and who got how many points because 2 loud sounds play on top of each other and last for an extremely long amount of time. The best solution is reduce the volume, the problem? Now you've reduced the volume of the quiet, nice and proper background sounds as well.
Probably the best game over there in terms of sound design would be Farkle, compared to our version, there are sounds when a player overtakes the current leader/when the score limit is reached and everybody gets a final turn.
It's a completely different story if we are talking about audio games, where sounds are the central and the main point. Here, they are supposed to give you an idea about what is happening in the game, but not to blast your ears.
I wouldn't call the current sounds low quality though. If we want to move this topic forward, probably the best idea is instead of RS games comparisons, to point out the sounds that you currently don't like. Obviously this is going to be quite subjective still and not everything will be changed as it's impossible to make everybody happy, but I would myself be curious about which sounds users generally don't like.
