I've been looking at payment processing options. Without making users create a separate account on PayPal, it looks like my only option would be have a monthly fee in order to have the capability to store and process charges directly. The monthly fee would be $30, which means I could actually start losing money if no one wants to upgrade their account. Not an ideal business model. haha
So, I came up with an idea. I created GT with the idea that I didn't want to give people advantages over others through time (where a person who can sit and play all day gets a leg up) or money (where people can buy upgrades), but that was also back before there were multiple worlds. I'm going to add a weekly world soon to accommodate people who can't play every day, so I thought I'd try a variation on the second idea, too.
I'm going to create a world where users will be allowed to purchase game money with real money. $1 will buy $100,000 in the game. The concept never really sat well with me, but I thought about it and realized that people won't be forced to play on the world if it's something they don't like. And even if they do play, they certainly don't need to purchase additional income.
I thought it might be a good way to try to generate some income from the game. My dream is to some day get paid to just sit and come up with new games for all of you to play.

Let me know what you guys think!
