My parents bought a 5200, but we never played it all that much. I do remember losing to my Dad in football every time we played. My sister and I split the cost of the NES. We couldn't find the Super Mario bundle, so we got the first one we found...the R.O.B. set. I loved Duck Hunt, but absolutely hated Gyromite. I was able to hook ROB up and get it to work with Gyromite, but it was such a hassle. I remember we bought Castlevania very soon after.
The first console that I bought all by myself was the Super Nintendo. I remember having both the SNES and the NES hooked up to one TV. My Mom wouldn't let me put one in my bedroom when I got a tv, so both had to be in the living room. I also remember saving my allowance in order to buy a subscription to Nintendo Power when it first started. I was pissed because they were going to start charging for this new magazine when the Fun Club News was free. Once I received that first issue as the tryout issue, I was hooked. Nintendo really knew what they were doing with that giveaway.
Oh, and my Dad and I only played 1 game of Tecmo Super Bowl on the NES. I showed no mercy. Maybe that's why we only played one.
