New to SaGa. How should I start the new upcoming remake?

Ever since about 6 years ago, I’ve fell in love with RPGs. Especially retro ones. And I’ve always wanted to give the SaGa games a chance but had no way of doing so, and whenever I do see a game I want, other games get in the way. But now that Minstrel Song is coming out on switch on a few days, and it looks very retro/old school 3D (one of my favorite old school retro looks. Reminds me of Grandia 2 kinda.), I decided to get it and pre order it on switch. All I know is that there are different characters to start as. Who should I start with and what should I expect with the game? Since there are 8 main characters (from what I’ve seen so far), should i do 8 playthroughs to do everything? I won’t mind doing that if the game is good enough and from what I’ve heard, this game is amazing.
