What does that necessarily have to do with anything? Her "hurrying up Gordon" could easily have made sense from a story standpoint. I have no issues with the pacing of Half-Life 2, but there are many times that the amount of "freedom" a game will give you takes away from the urgency of the whole situation. "Oh no, it's a big giant meteor coming towards the planet! I'm going to hang out at the Golden Saucer in the mean time." I was enjoying Final Fantasy VII (and still did enjoy it), but when I realized that the urgency was all just a facade, it lost a bit of its lustre.
While I may be a decent enough "twitch-reflex crack-speed FPS player" (given the large number of games I play, it couldn't really be helped), I certainly don't consider myself to have a short attention span. One of the things I really hated in the original Splinter Cell is when I lost a mission because I was responding to Lambert's urgency that some event not be televised. Because I didn't bother hiding the odd body, I "set off alarms" (which was a retarded mechanic in the game), because I figured that rescuing the hostages was of the utmost priority.
Seriously, simply labelling someone that might not hate the urgency as having a "short attention span" would be like saying people that don't want it have ADD or something.
