yeah totally buy it, then get the business edition when you have $5,000 and you only have to pay $480 according to the licence uela once you have more than $4,999 you must buy the business edition to continue making money, and who knows if you market correctly and set the right price on the store of the markets you could become a millionaire in a matter of hours, all depends on the quality of the game and how good it is and how fun it is, and then you just have to experiment with the pricing of the game on multiple stores... One other key factor is that your games are original and with your own resources and that your not infringing on a copy right of another game or stealing their resources, or engine.
