I've only played 0 and 1. I would not listen to him and I would play 0 first and then 1. Playing it in reverse order would have ruined 0 for me. Play 0 first and then 1. 0 is only $20 and I can tell you right now it felt like I was ripping Sega off.
I'm all for welcoming opposing opinions but when you've only played 2 out of 7 games and say "don't listen to him" regarding which order to paly them in it's kind of hard to take you seriously.
I am currently sigless.
