Graphics, smaphics. Graphics are like special-effects in movies: they enhance the experience, but they aren't a replacement for storyline. A game with super-high-end-strain-your-$1000-GPU graphics but a craptacular story is a loser compared to a game with only so-so graphics but an engaging & entertaining storyline.
Think about Starcraft -- not the newer Starcraft II, the original one. How many games from 17 years ago (Starcraft came out in 1997, the Brood War add-on in 1998) do you still see for sale in stores or online? Even games like Combat Flight Simulator 2 (released in 2000) have long disappeared from the "bargain" shelves in the stores. Yet you can still pick up the "Battle Chest" version of Starcraft (including Brood War & the strategy guide) in stores. That's because the storyline keeps you engaged, even though it predates the use of true 3D graphics in RTS games. And that's why fans were glad that Blizzard took so long to develop Starcraft 2: we didn't just want better/updated graphics, we wanted a great storyline to play through.
Besides, once you start going over 60 FPS anyway, you're not actually seeing any visual improvements. So as long as your hardware easily runs your games at 60+ FPS at the resolution you game at, the rest is just simple posturing.
