it could be anything
for me, i just miss the wide variety of games available - you had almost every genre: shooters, fighting games, puzzles, platformers, RPGs, side-scrollers. that and i miss when video games had interesting plots and characters. nowadays, it's all about high-tech, state of the art graphics, little variety in games.
i also miss sega as a console developer- ok, their only success was the megadrive/genesis but the dreamcast had great games and saturn wasn't too bad. it's a shame they went away the way they did, although their business decisions was what led to them exiting the hardware market.
nintendo vs sega was quite fun actually- it may have been heavy handed, but the console wars back then was no where as competitive and dare i say it, catty and nasty as it is today.
I was the Segarian and my old mate was the Nintendite, ha ha! we had the best of both worlds at the time. I remember when Mortal Kombat II arrived at arcades and there were huge crowds gathered round with competition at maximum overdrive you don't see that going on these days
I was blessed to have a 33.6k modem and downloaded the full lists of moves, fatalities, animalities, babalities and friendships and proceeded to pump out hundreds of copies using the school xerox then sold them for $10 each after school at the local FX Zone arcade in rural city of Wagga Wagga. I made enough cash to buy my SegaCD + 32X add-ons for my Megadrive along with a backpack load of games
