You've seen people comparing Suikoden to CoD? But that's like comparing it to Madden or Fifa... the titles aren't even remotely similar... 
Well, I wouldn't worry about it. "JRPG" is almost a taboo term even on this forum, and this one is pretty civilized (all things considered...). IMO it's better to know the boundaries of the game in advance than have a lot of superficial freedoms but then run into severe restrictions at the times you would most appreciate flexibility in the story or the main character's actions (example: Skyrim NPCs that are immortal unless you are on PC and mod the game... and it's always the most blatantly annoying NPCs that cannot be killed...)... most JRPGs don't lie about what they have in store for you, and unlike many, the main characters in this series are pretty neutral and don't make a lot of faceplam decisions (with a few exceptions...).
The other thing that's odd is the idea that someone wouldn't find 6-8 people they like out of about 80 or so playable party members (I know there are over 100, but some of those are castle staff that can't fight, I think...). Even if somebody rubs you the wrong way, you don't have to use them, and sometimes you don't have to recruit them at all... that's a lot of flexibility, especially for a game that came out so long ago! Well, w/e... I'll be enjoying it nonetheless...
There does seem to be a lot of JRPG hatred for whatever reason... I wonder why. It looks suspiciously like haters gonna hate... honestly. It could also just be a strength of will thing, many people just can't complete long kind of campaign type games.
Anyway, I just wish people would use their own personal sentiments as a way of judging a game and not simply hold up in front of all the masses and use them to extract a populist opinion, or rely on fictitious gaming rules like linearity = bad. For example, aren't movies more linear than JRPGs? Sure, JRPGs might be somewhat linear, but compared to a movie? And yet, no one goes, this movie isn't open world!
Suikoden 2 is not the type of game that works in that bizarre framework people have constructed for "judging" games (and which isn't very useful anyway), which mostly consists of 98% random arbitrary rules and twitterized snark and 2% personal opinion. It's just the type of game that can be a ton of fun if you sit down and play it, you know, for fun. The creative output in terms of characters and narratives is overwhelming, especially compared to a typical western game, most of which struggle to create one character, let alone 108.
And yeah 108 characters, but like 30-40 are non-combatants.. approximately. Personally I enjoyed many of them at any rate so disliking a few here and there was not a big deal... was never really a fan of Fitcher for instance.
