Ut2k4 is so fantastic, I still have a scar on my forehead from the first time I played the demo on a CRT sitting on a chair and my friend tackled me into it to "save me from a sniper". I would get up at 4am because I had a bedtime but no wakeup time and play 4 hours of CTF-Face instagib before school. Q3DM17 also holds a special place in my heart, I'm getting a tattoo of the "Impressive" emblem in a few weeks!

Not a day goes by that I don't pine for turn of the century FPS gameplay. (and maybe my turn of the century reflexes)
