Games in the PS2 era, they were mindblowing to me, there was "something" feeling different (then I learnt it was the 60fps), it alone was another gen for me apart from graphics... I mean, coming from N64 and PSX and those framerates, lmao.
Super Mario Galaxy is another game I remember being mind blown, and I played it using composite cable (the ones with 3 colors only) and in a LCD TV... The curius thing is that I already played HD games on Xbox 360 on an HD tv before (which, btw, also were mindblowing).
