Here are my honest opinion ideas:
All skaters (Including Big Black)
City - Give it a new name and base it off of the East and West coast, maybe throw in some random middle USA-like spots. The City needs a Day/Night cycle.
Clothes - 10-15 clothes for each brand. Include custom t-shirt, long sleeve t-shirt, plaid shirts and plaid pants (Gives you 2-3 color options), the colors we see in Graphic Creator and let us choose pants size options such as: Skinny/Tight, Fitted, Baggy. Give us way more shoe options! Monster, Amp, Red Bull, Rockstar and all the energy drinks should have clothes.
Boards - We deserve things like 10-15 decks per brand, Custom Griptape, Berrings and custom Trucks
Tricks need to be improved by adding:
Impossibles
Cigarette Flips
You get it the unique flips.
Skate.Parks
You should get unlimited space for parks and way bigger maps and even throw in a Create your Own City. We should be able to DL unlimited parks (Idk max, please tell though)
You heard my ideas and I hope you all enjoy it.
P.S. More advanced body customization
