is justly considered a classic
, and is *still*, 7 years later, the best shooter ever made
. Its rules, its physics, its weapons are as simple as they are unrealistic. Yet, it is a perfectly oiled mechanism that you will go back to because it works just right
Because its simple mechanics give you that sense of satisfaction to have played well (or at least, given your best) against worthy oponents, in a set of rules where only your own skill
, not your hardware, achievements, level, buddies, equipment... made the difference.
Because it is very immersive
, despite the unrealism of its setting and dated graphics: its physics, its actions, its pace are just defined by running, jumping and shooting, not encumbered with clunky, over-designed interactions in the name of "realism".
Because it just works
: no bugs, imbalances, lag, slowness, flakiness, choppiness, unresponsiveness, bloated interface, unintuitive design, complexity get in the way of playing.
You will simply come back to it because it is The Game
, stripped of all the un-essential.
