Working with Comunity edition in Game Development

Hello, 

A friend of mine and I, started to develop a game using an opensource FW for 2D games and we want to make a game that we would like to publish later on platforms like Steam. (and maybe sell it / maybe start a kickstarter etc.) Can we use comunity edition to develop such software or do we need UE ? Cause Im also an app. developer andi work for a big. corp. but there, we were specifically told to never use comunity edition for work. So its kinda unclear to me what is the difference.
