i666an: The legal 1 is the 1 that bothers me most now. Heck I just wanted to give someone a gift :)
Let me put it this way. No one will frikkin care.
But no, you can't. Generally, unless it is explicitly stated (and even then it is rather complicated) you cannot trade licenses you personally bought from any digital retailer. That means any game you buy, you buy for you. That is also the reason you would need to use the gifting options if you want to gift something, digital gifting is legally a different mechanism than, say you are gifting a CD to somebody.
Some bundle explicitly stated that you can in fact share unwanted keys (which results in legal clusterfuck those bundle sellers obviously didn't think of). But with enough creativity, it would be legal.
I took a look at the terms and conditions and I couldn't find anything that says sharing the keys is deemed OK by groupees.
That being sad, the laws should be pretty much the least of your considerations.r Especially as it is very unlikely to expect trouble from this.
But you should take a moral choice on this. The package is a "pay what you want package", that means you probably paid only the amount you would pay for the games
you wanted, not for the whole package. Therefore giving away the other keys is morally similar to piracy, because no income was provided.
I personally am very OK with piracy and don't have a problem if people that can't afford games get them for free, one way or the other. But how you feel about this is more important.
