Retro gaming isn't just a state of mind, it's a way of life!
I play my Amiga more than I do my Xbox and PC combined, heck even my C64 get's more mileage.
One thing I find personally with retro games is that's it's easier to reach a Zen like state of mind, you often find that your skills as a gamer can be tested to the absolute limit and often beyond breaking point. Concentration, aptitude and mental agility as well as cat like reflexes are common requirements for many of the 8/16 bit games out there, but that mainly constitutes for the computer side of gaming. Console games however have always tended to have a far smoother and learned difficult curve, thus being the most commercially successful and accessible to the general public. I tend to gravitate between the two depending on my state of mind.
