Well more realistically how about some nice graphics for existing games ? Make it more interactive. Some good sound effects go a long way too, but don't make them too repetitive people end up muting it.
I want to see independent Bitcoin casinos, real dealers for live poker games. Right now almost all casinos use standard systems, coming from external sites. I want to see a Bitcoin only casino site with beautiful Eastern European dealers.
That sounds cool. Innovation and offering something different always goes a long way.
I don't play poker but I enjoy playing games against people or even with so playing poker live would really be something.
Oh and I was on a website the other day that used btc and had women from all over the world. Not that I really care xP
