I'm an artist at heart with the urge to be unique so I need more options and things to make it easier to be artist to my limits so I HAVE SOME IDEAS.
BUDGET CHANGE: Instead of putting a limit on pieces, since there's already a limit on money, take off the piece limits and only money limit.
REWIND/UNDO OPTION!!!: Please learn something from LITTLEBIG PLANET such as...
GLUE TOOL: When making a building from scratch, because I like to be unique, I want to be able to make a building made out of a million little pieces get glued into one piece so I can move the whole building when something very important comes to my mind that changes the map drastically.
TUTORIALS: FOR GAME TYPES ESPECIALLY. Learn something again... LBP has tutorials for EVERYTHING...
MORE PIECES/THEMED CHANGER: For each theme in the campaign, add different pieces that come from that theme, like gold pieces from Halo: Reach's Reflection map, purple covenant pieces, OR just add theme change for every piece.
FIX OVERLAP DISCO GLITCH: When pieces are over lapped, they tend to look like a disco ball when you move around, please fix that.
ADD WEATHER: My friend wants to add water in certain areas, WHEREVER!
HOPE I DIDNT FORGET SOMETHING!!!
