At this point, what is this thread about? Noone answers the question of the OP anymore, which was arguably pointless to begin with, and no people are attacking/defending a game they never played. This has been kinda run into the ground.
Truthfully it seems about anything you want it to be in terms of Splatoon's general launch plan more than anything and it's easy to feel like everything's just repeating on itself a little no matter what side you're on the issue.
Either it's about the price point, it's about content, it's about the post-launch support or all of the above.
The realistic scenario judging by the reaction here the way I see it, if we bring it back to just the "review" point of the topic, is that if the general quality of the launch content can't sustain it's longevity, we're probably looking at Killer Instinct or Ground Zeroes-esque reviews - games that were heavily lauded for their game play but criticized on the quantity of their content.
Price point is a sore issue for the American side of things and I agree on the stupidity of segregating the price points, but not something I necessarily see many reviewers actually factoring into their judgment. It's going to be based purely on what's there and if it lasts. Private lobbying is something that will probably be more of an annoying point to deal with as something that will actively reflect on reviewer judgment, and that's another factor I also heavily think Nintendo bungled up.
But the way I see it if you have any passing interest what-so-ever in the game itself, chances are you're in one of either two camps. If you think you'll enjoy the game already based on the quality of it's content, people will encourage you to jump into the experience and ride with the content wave. If you think you'd rather hold off on it until more content arrives, it's also a good choice. Splatoon is in it for the long term and is only a game that will get better with time. You probably won't get it for a better price point considering it's Nintendo, but I guess that's just the lame stuff we end up having to deal with.
One thing's for sure though and it's that I really don't think the title would face this much scrutiny if people didn't actually care about it. I can only hope it doesn't screw up.
