Ok it's about time I made a long thought out post about my predictions and wishes for Splatoon 3. I'm gonna address certain concepts I've seen in this thread, on Youtube, and my own ideas. First and foremost, I think the main selling point of the game will be weapon swapping. This would make for increased depth, strategie, and thus replay value, so I don't see why Nintendo wouldn't do this unless nobody on the dev team had that idea :U. It would either be its own mode altogether, in the main game, just an option in Private Battles, or in a second Ranked Battle rotation idk. Anyway, how would this work, you ask? You see, when you are on the equip menu, you'd pick two weapons. one would be your Primary Weapon, (the weapon you start with and are seen with at the end of a battle) and the other your Secondary Weapon. With the press of the A button (I know this can be used for throwing clams in 2, but you can also use the L button), you can switch from your Primary to your Secondary in about 40 frames. When you switch, you have access to the sub and special of the weapon you switched to. However, whenever you switch from your Secondary to your Primary, (or vice versa) the weapon you switched from's special gauge would be decreased by 50%. This would prevent using 2 specials back to back. Furthermore, you can't have a Secondary that is the same weapon class as your Primary. now the lore to it. When a scientist discovered a material that can shrink, he got it approved and now it's used in everyday weapons! Also, if Nintendo sees it unbalanced for some weapons to be switchable, they could always just have the excuse of that weapon not being able to be made in that material.
Now on to the single player campaign. I think that what they did with Octo Expansion was great. It had a decent story, introduced new characters and included old ones, and the stages were debatably all unique. Now, whether or not they could do it again only time will tell, but we can hope. I just wish Nintendo does what they think is best here like they always do, and in the end, Splatoon will always have a good multiplayer to make up for the single player.
Regarding Inkpolis itself, I feel like no major changes are required, but heck, it's Splatoon. One day a guy owns a shoe shop, and another he's broke and runs a food truck so, yeah literally anything is possible here. However, there is one kinda interesting change I thought of that would be really cool, and that's a movie theatre. As the Inklings found out more and more about human society, they discovered movies. They thought it was really cool so they decided to have a theater for themselves. When you visit the theater, you can watch the replays of the last 50 matches you've played IN SPECATOR MODE. That way, you could watch it from every point of view. This would allow you to see when and where you could've done something to greatly impact the game, see what other people where doing, what you did wrong, etc. to greatly better yourself as a player.
Now I'll address the pop stars that run the news. I personally think that there will be 3 stars. First of all, it would be another selling point of the game being that it is the third game in the series, but also it would allow for 3 team Splatfests. Now, I know what you're thinking "BUT ENPERRY, THAT WOULDN'T WORK BECAUSE THERE COULD B 3 WAY TIES", but there, my friend, is where you would be wrong. Splatfest would then have 5 was to get points - popularity, solo turf war wins, solo ranked wins, team ranked wins, and team turf war wins. There would still be a way to tie, however, and Nintendo can figure that out, but if it were up to me, if there were a tie, then the star representing the losing one chooses one. I really can't think of a better way to solve this so...
And if I can think of anything else, I'll add it. Thanks for reading this!
