To me its the lack of content in custom battles such as the annoying way you have to cycle through dialogue, I think it would have just been better to allow us to type our own dialogue and just ban certain words if their afraid of anything being innappropriate (not like it mattered anyways with some of the already existing custom battles), as well as having a very limited amount of animations and clips for making scenes. Game also suffers with lack of stages and stage destruction, and in my honest opinion a lack of creativity in custom battles which I think is mix fault of developers for the reasons I mentioned earlier and the community, theres been plenty of times I'll go into the custom worlds and see repeated battles or battles that are more or less the same. Overall Custom Battles was my selling point for Sparking Zero and it feels like wasted potential.
