As my colleagues noted, you clearly need an attorney. The fact that you directed this video without a contract, makes it difficult for you to prove what your payment rates were, whether you even WERE the director (as opposed to a producer, grip, associate etc.) The fact that they want the hard drive is your leverage at this point. Seek counsel immediately.
It's really a fact determinant question, based on how the card looks, what text is on there, etc. One question will be why you need to use an Apple computer in your card artwork, as opposed to any other generic laptop. If you look at most popular card games, like Illuminati or Magic, they tend to avoid implicating other trademarks where possible.
If you were going to sue, you were going to sue 26 years ago. Perhaps it happened and you didn't know it. Perhaps your mother was advised by counsel that it was a losing case. in any event after 26 years, you're not going to get to dig up the old skeleton. Incidentally, as someone in their mid-thirties, it's preferable to use proper spelling, punctuation, and grammar; your question is nearly incomprehensible.
Screenshots from a Facebook account are not inherently inadmissible; however there may be evidentiary reasons why a particular screenshot is not admissible. For instance, it may not have probative value, or may lack authentication. A divorce attorney will be familiar with the rules of evidence and will know how to properly get the screenshots admitted.
In theory, yes, it is possible. The odds you'll be arrested are slim, but more importantly the odds you'll be scammed by an illicit gambling site are incredibly high. Since they're located outside the U.S., you have essentially zero recourse when they start adding fees on your account, or outright seize your money. Happens all the time. Or they violate some local law in their jurisdiction and have all their accounts frozen and you're out your entire balance. Do yourself a favor. Go to one of...
You're asking a question far too specific to be easily answered on Avvo. You should consult a gaming attorney. I will, however, note that with the first one, it is irrelevant the form of the payout, be it bitcoin, or gift cards. The important thing is that it is something of value, which all of those things are. In any event, Avvo.com is no substitute for spending the money and retaining an experienced gaming attorney.
It's irrelevant that you want to make the game without using prior existing mechanics or characters. You want to use the Star Wars logo and key Star Wars sounds. You will need a license to do this, and as a practical matter if you are making this game from scratch (as opposed to a mod from a game), it is highly likely to get shut down by Lucas Arts/Disney should they find out. It is in their best interests to do so -- you making an unprofessional game using their intellectual property,...
You really should try punctuation and grammar some time. It is literally impossible to understand what you're saying.
Also, if you have an attorney already, you should be working with him, and not asking for help on the internet.
