- If sucessful Splatoon and Sunset Overdrive may influence other shooters to
A) Utilize creative modes of travel
B) Utilize creative weaponry
C) Utilize a more interesting color scheme
Well, if we come right down to it, I'm not sure either of these games are doing anything all that new or special in any of these ways, which is why your declarative statement in the thread title is causing such distraction. Your reasoning doesn't really track with the thought.
Creative modes of travel - I'd argue Splatoon is far more innovative than Sunset Overdrive here. The fact that your ink opens up faster travel, and that ink is dynamic based on where your team sprays it on the environment, makes it undeniably unique. But so unique that I'm not sure it's a mechanic that could really be borrowed by other games.
SO is just really compiling things that many other games have already done many times into it's movement system in a (hopefully) slick way. We've seen rail grinding increasing movement speed in countless games, from Tony Hawk to Insomniac's own Ratchet and Clank series. Even other open world games like Infamous have used the mechanic as modes of character locomotion.
Creative weaponry - Splatoon doesn't seem all that creative on this front, as most of its weapons just seem like your usual weapons in a third person shooter with a slight "ink" characteristic.
Sunset Overdrive definitely has wacky weapons, but that is par for the course with Insomniac games, even in their "serious" games like Resistance, and the combinations of different items to make new crazy weapons against hordes of enemies in Dead Rising doesn't make SO feel particularly innovative on this front.
Colorful art direction - Splatoon isn't really all that different from any other Nintendo game in this regard, except it looks like it just has uglier art direction than their flagship games. It looks like a crappy kids cartoon on Nickelodeon from a character/environment design perspective.
Sunset Overdrive has a more cohesive "voice" to its style, but it doesn't look all that unique. Enemy designs look like amalgamations of things we've seen in games like Left 4 Dead's bloater and any other generic "monster" designs from many other games, from Far Cry's trigen to Doom 3's hellknights. Character design is kind of your usual punk/"attitude" look with cutoff denim vests and colorful shoes and bright logos that we've seen in things from Infamous: Second Son to even the player avatars in Rock Band. The most interesting thing they are doing visually is with their explosions, which is obviously borrowed from comic books.
Outside of that, nothing in the games stand out as particularly new or innovative. Splatoon is just another variation on team-based shooters, and Sunset Overdrive is another open world action game. That's not to say the games look bad or anything, they both look perfectly competent with great promise.
Certainly nothing that would make waves through the industry leading to direct inspiration among and outside their own genres, like your Halos or Uncharteds or Call of Duty 4s or Team Fortress 2s.
