I have fond memories of playing Quake 2 for some time and then buying a Voodoo card. It suddenly looked like a totally different game. It wasn’t just the resolution and texture filtering - Quake 2 in GL mode used a totally different, dynamic lightning system and back then it was simply stunning.

I was quite into QWTF (the original Team Fortress) and being able to use OpenGL allowed you to have gorgeous see-through water. This was a massive advantage because players tried to avoid snipers by going through the water. Also super useful on well6 in the flag room. Ah, the nostalgia.

The original pay to win. Another classic one was being able to afford (or live at university dorm) a good internet connection.
