I had a PS1, way back when - mainly to play Tekken 3, which I was hopelessly addicted to.
Now, I am purely a PC gamer. I think the PC is the most flexible gaming system, bar none...and most easily upgradeable.
However, I really do miss the days when games came out for PC first, then trickled down to the console systems. I think it really stinks now that you've got to have console X to play Game Y, because they're exclusive to that console
