What was your first videogame that made you say "Ok, I need to play this game properly: I need to upgrade my specs"?
Going back to your beginnings in PC gaming: the first game you played and loved, but the frame rate and resolution weren't ideal. Your first "I need/want to upgrade my specs" basically.
I can't recall exactly which one of the two it was but it was either Quake 4 or Doom 3. I remember I managed to squeeze out like 14 fps using RivaTuner on the family computer. I got my first job not long after that and put together my first PC.
Doom 3 for me by far, I remember reading the pcgamer article and it was the game that they were predicting would cause millions of upgrades. IdTech at the time was incredible with what it was trying to do, and they weren't kidding. Kind of funny that it's so accessible these days.
