Not money, but ideas, gameplay, philosophy, user interface design etc. When you see a good idea that’s succesfully used in some context, try using it in your game or in your business. Maybe add thing or two to it. For example, web hosting companies use ‘live chat’ on their websites. Maybe you could add ‘live chat’ for your software’s buy page – and respond questions from potential buyers.
Or maybe you see a really nice website template – could you perhaps use that as an user interface in your game?
Or maybe you have read a good book about customer service – maybe you can use the same ideology in your business.
Learn to steal, it’s good for your game business.
