because it was an FPS with a storyline and some unique puzzles in a time where FPS have no plotline whatsover and just about bang bang finish level

no idea why either....i've played thru both of them...but just not my type of game i guess....i only have them both because of cs...i guess i need more realistic weapons...that's probably why i also like cod series and hate any halo, quake, unreal, etc series.....

Well I remember playing Half Life 1 as a kid and while I enjoyed it it didin't still seem so huge...
I played Half Life 2 pretty late, around 2-3 years after release.

I played it on PS3... before that... NeVER.. just because I was a stupid DOOM fam... and didn´t saw next games comming;;;

when I played Episode 2 and next half one... I stayed amazed... soo cool...

soo... they rulez!

never understood it at all

to me there were tons of better shooters at the time, and as far as a narrative shooter goes system shock 2 shits all over it
