What do you mean by "[solitaire is] not as much of a game when compared to, say Halo"?
It is possible that Halo will be around in 100 years, but I am pretty sure solitaire will be.
Don't get me wrong, I love my videogames... but sadly I am also one of those who cannot dedicate large chunks of time to one nowadays.
I see Nintendo still working on their IP (Mario, Metroid, Zelda, Excite, etc) and trying to build new ones (Sports, Brain, Pikmin, Chibi Robo)... Of COURSE I wish they could do more, but I'd rather them do good stuff than push out volume.
