As a whole it comes to mind that we still know very little about this game.
We don't know if there's a campaign. We assume there probably will be, but no idea.
We don't know when it actually comes out.
We don't know how much content you start with. We DO know they want to do free DLC like the first game.
Will there be splatfests?
How well will the online function when we are actually paying for it?
@KaizokuJinbe: I actually disagree with you. Sure, I haven't played the game, but just from a distant glance into what is happening in the game, it is very much not a carbon copy. Or maybe as much of a carbon copy as Project M is from Melee. Not to mention that the "rollers are OP" mentality lasted about a month for most people, much like how the Smash 4 meta began with "Little Mac is too strong"
Gear working differently will make the game more accessible to a lot of people.
Specials seems considerably less powerful so far than the ones in the original Splatoon. Nothing so far can control an area or a match as tightly as something like a Killer Wail, a well-timed Kraken/Bubble Shield, an Echolocator or even an Inkstrike. At best, the Inkjet kinda has a similar function to the inkzooka, but where the inkzooka was able to fire quickly from one spot, the inkjet requires positioning and exposing yourself to the enemy team. And then there's the Stringray, which announces itself like the Killer Wail but fails to instantly kill.
What I'm getting at here is that this game seems to reflect a meta where specials are still strong but have more isolated impact, and perhaps as a result will probably also charge faster. With stages also being for the most part completely different, it's really hard to say where the meta will actually go.
So basically:
- If you played the original Splatoon a couple of days/weeks and then forgot about it, this game will probably feel very similar based on what we know so far. Single player campaign may change your value of this game.
- If this is a game you spent hours and hours and hours playing to get to S rank, and still kept playing because competitive was a drug you hated but couldn't drop… then I'm fairly certain this will provide a relatively fresh experience with the same fun mechanics we are used to. The changes with specials and how some weapons work alone ensure it will be different in the same way one smash game is from another. In this case, I would say the game is worth getting, though I personally wouldn't suggest getting the Switch just for this game.
I think this game in the end is worth getting most for people who never played the first one due to not having a wii u, and people who went all in on the first one.
