The fact is that Half-Life 2 still executes its concepts, conceits and mechanics more effectively, deftly, and powerfully than almost any of its imitators have in the 10 years since. It’s no aged benefactor, thanked yearly at the annual commemoration ceremony before being shuffled off back to the care home. You see while Half-Life 2 undeniably laid the foundations for a staggering proportion of the then-future of game design - genre be damned – it is no mere historically lauded precursor. I say this not with nostalgia, or spurred on by a curmudgeonly knee-jerk against the smoky linearity of the modern military shooter (in truth, a dominant genre now only in the minds of those still affronted by its last-gen ubiquity).
