Coding the game is the easiest part of it all. Getting the artwork is indeed the hardest part about making a game. It can also halt the entire process for a few months, while the team waits for a graphics person to come along.

Slackers are worse than having no graphics. If you have one of those as your leaders. You better go find another team, because you might see those graphics in a few months.(only if you try to get someone to join)
