Push harder for what, exactly?

In my experience, the best game developers are primarily motivated by their desire to create awesome games and their motivation level is already maxed out. Some see shares and other bonuses more as a sign of distrust than as a motivator, as if their dedication to awesomositude is being questioned.

Besides, awesomest isn't necessarily most profitable, so if you encourage your team to optimise for profit, there's a pretty big risk that the awesomeosity output rate will drop. With time you might even end up with a team churning out click-grinding Skinner boxes, which is not very awesome at all.
