Similarly to OP, last Saturday I also played my first game at GGpoker (due to the fact that I'm also stricken by banning of the country, so cannot play on the PokerStars anymore), and found it to be very amusing in some way (with music, emoticons, delayed river card,...🙂 )
Although I played the game on the computer. I am now, very intrigued to see, how it looks on the mobile app.
So far, I think that the biggest difference between PokerStars and GGPoker (aside of the versatility of mobile client app) is that, that PokerStars has more games available for people to play with lower micro buy-ins, than that I can see are available on GGPoker.
But this does not meter anymore for me, because I cannot play on PokerStars anymore, so this post of mine is slightly loosing the meaning and the sense 😀 (I think that I missed the question of the topic, sorry for that)
Anyhow , cheers all and have a good game 😀
