Sega had more consumers then Nitendo...i owned both systems...i am not biased to either one.
200$ back then was worth alot more compared to today.
read that...Sega won the console war against SNES
Ok just found out...Atari was also priced at 200$
sega as you said 189
but back then it was worth more(200$back then is a bit different than 200$ today)
