I know this might be very complicated but, it's just something I'd like to see.
A couple examples so you get the point.

Let's say i'm in the forest or somewhere else, doesn't matter.
1-I use Earth Style Earthquake, nearly  trees are going to fall and others just move side to side.
2-I use FireStyle FireBreath aiming to a tree, the tree may just fall or burn.
3-I use any powerful technique that interacts with the floor/land and it makes a hole just below you or the opponent, or wherever you aimed it to.(like the ones in the picture, also you may remember something like that in DragonBall)

The last one might depend on how strong the technique is, I mean, something like the RasenShuriken should make a bigger hole than the Odama Rasengan.
I'm just giving examples!I know jutsus like rasengan are not going to be in the game...I don't think so 

I don't know if I'm making myself clear.
This is all I can think of, but I bet there could be more interactive things.

Maybe in some future this could be included with buildings too.



Thank youu

I don't know you guys, but I'd like the ability to climb a tree and start running through the trees as people can see in the anime/manga.
Since NarutoUniverse is a really really big world (I don't know if Shinobi Life Online is going to be a limited world) we should have the ability to run through the trees, not just for the reason of running really fast but also because that would be awesome! haha

Thank you 

Maybe at some point, if this goes farther, you could get official use of names and staff.
