Ok, I'll answer your posts in a nice way^^
1. I was thinking about adding it, nice idea.
2. I like this idea, but how would it work and would Half-Saiyans be able to fuse with Full or not?
3. I like the shake effect cause it makes it dramatic and adding voice seems sorta I dunno, dumb I guess?
4. At the moment, I'm working on some hairstyles like Tapion, Uub, Etc. and some custom Hairstyles too.
5. In a way The Gi and Stuff makes you look like a customizable version of Goku or any of the normal Z Fighter outfit.
6. I wouldn't mind houses in the game, but buying stuff in your house again, seems kinda dumb.
7. There is something like this and We rarely ever have any pwipes.
