There's not really anything to take for granted IMO. I'm not a big console gamer anymore. I dumped my xbox when the drive went out, now the newest thing I have is a PS1, but I will buy another console sooner or later, like if GT5 ever actually gets released. I grew up on Intellivision and C64 and went through the whole progression. Video games/computers are the one thing in this world that I know barring armageddon will continue to improve as time goes on. For as long as I can remember I've been saying "think how great video games will be in 10 years" and they haven't disappointed. My only real beef with modern games is they are quite frankly too damn easy. There is no more "Game Over", now it's "You are dead, press X to respawn and keep going". My buddy rented Uncharted 2 a while back. It's honestly probably the best game I've ever played, good storyline, good gameplay, and absolutely stunning visually. The only problem was we tore through it in no time and when I went back and looked at the stats I think it was something like 8 hours of game time it took us. It left me wanting more, and there's no way in hell I would drop 60 bucks or whatever a console game costs these days on it.
Kind of off topic, but for those of you who are old school type gamers I recommend the movie The King of Kong: A Fistfull of Quarters. It's a documentary and the people in it are out of this world, and it goes way back to the glory days of the arcade.
