Most NES games--MOST!!!--would be about forty times more difficult for me without savestates. The thought of doing Kid Icarus or Ninja Gaiden or Castlevania....arrgggh. I loved how AVGN just DIDN'T beat Ninja Gaiden because of that jump he couldn't do. Thank God for NESticle (the readme file that comes with it is beyond hilarious, too.)
I'm really glad I never bought the original NES, which is what I was planning on doing in 1991 when the SNES came out. I didn't want the SNES and thought Mario World looked like crap based on magazine ads. I got the SNES anyway, which pissed me off as I wanted Super Mario Bros. 3 in my life more than anything else in the world. ANYTHING. When Mario All-Stars came out I must have had a buttgasm. (The previous sentence was written just as I got to the part in Cream's "As You Said" where Jack Bruce goes "I'll never come again....agaaaaain....AGAAAAAIN!") It was so PERFECT that Nintendo did that, which made me stop thinking for a few minutes about what turds they were for getting rid of the blood in Mortal Kombat (it was 1993.)
There's a huge retro gaming nostalgia store around here that's full of those SNES RPGs that cost $200 for the cartridges now and they've got back issues of Nintendo Power that I've considered compulsively buying--I got rid of most of my gaming magazine back issues years ago, but wish I hadn't. (Except DieHard GameFan, I still have loads of those.)
