the half-life anniversary update is reminding me of The Chart, aka what i break out anytime someone tries to talk about first person shooter game engines to me. i had to find this when i worked at Activision to understand why one of the things i helped bug was marked as "Will Not Fix, it's a bug that's existed since the previous quake engine" (it later got fixed anyway).
I was actually, legitimately, one of the top Urban Terror players in the entire world at one point 😂
