A word or succinct phrase for "capable of producing financial income"

I have a bullet point list describing some requirements for a game I will be producing. It is written as follows:

The game will be:

• Requirement 1
• Requirement 2 ...

One of the requirements is "capable of producing financial income", but this is a bit of a mouthful.

At the moment I have the word "monetizable", but that is a bit of a miserable little word. Are there any better suggestions?

Solution 1:

There's nothing wrong with "monetizable". Some dictionaries haven't yet caught up with the now-widespread usage, but it's a perfectly regular extension from...

monetize (verb) To make a business activity profit-generating, particularly in computer and internet-related activities. [emphasis mine]

Noting that highlighted element above, I'd say it's perfect for OP, not "a miserable little word".

Solution 2:

Moneymaker: something that produces or yields much pecuniary profit.

Revenue generator: A revenue generator facilitates revenue generation.
