Legal Question in Technology Law in Oregon

Re: Does my program I've made break copyright laws

I doubt you would be breaking any copyright since you did your own graphics and programming. Copyright infringement is decided on a case by case basis, the question being how much of the copyrighted work you copied. So, if you are trying to simulate the look and feel of a copyrighted videogame there is at least a remote potential for copyright problems.

If you steer clear of any trademarks involved with the game you are simulating and use somewhat different coloring and use original card designs, you increase the safety of your position. Not only that, you increase the chance that you can protect what you do against copying.

I think it is worth you speding a $100 or so for a half-hour consultation with a copyright lawyer to be sure you both avoid copyright infringement and maximize the chance of your obtaining useful copyright protection.
