Three games to choose, what to start?

So I recently finished soul sacrifice delta and persona 4 golden. I have three games in mind to start, I played a little hyperdimension neptunia mk2 but I stopped it because I own far better games that this.

So the three games I am thinking to start are:

-Ys calestial memories (ps vita)

-Shin megami tensei nocturne (ps2)

-suikoden II (psx)

Heard Suikoden II is one of the best games ever made. You should probably start with that (I haven't played it so can't say for sure).

I'd strongly suggest Suikoden II. The story is fantastic.

have never played Ys but Nocturne is a really boring dungeon crawler unless you're into those kind of games like Baroque. Suikoden II on the other hand it's a classic. And it's even better if you played the first game and got all the characters so you can unlock the protagonist of that game on part 2.

So we have 3/3 on suikoden II. I'll go with that. I also saw very good reviews about that game. I wanted to play nocturne because of the mature storyline and dark atmosphere (at least that's what the people say about the game).

All of them long games, does it matter :P?

I'd start with the PSX game
