Xenoblade Chronicles X - more Skells talk from executive director

These following quotes come from a Famitsu interview with Tetsuya Takahashi,  who is the executive director for Xenoblade Chronicles X...

Why there were many designers working to create Skells, characters and weapons
''There are two big reasons. First, there are several forces with their own culture. We wanted to give each force and corporation their unique characteristic similar to how the designs of Toyota and Nissan differ, although both of them are Japanese cars. The other reason is that there are many different equipment in this game and it would be hard for one designer to create them all. That is why we asked several designers to work with us.''

About the Skell's super weapons
''Super weapons are very powerful weapons but they aren’t easy to obtain. They were implemented as an objective which keeps the player motivated after obtaining a Skell, but we also wanted to create strong weapons and weapons which change the silhouette of a Skell. Please obtain them and use them for the changed appearance and powerful attacks.''
