Nobody is denying that the OP has been through a hard time and I sincerely hope he is feeling better now. I don't think he deserves punishment or anything like that, but the fact is, he gave people some games with no obligations.
He has no right to ask for them back, it's as simple as that. I'm sure nobody on this forum wishes any ill on him, and we're certainly not trolling, we're just pointing out what's obvious here.
My apologies if I've upset the OP, but I genuinely think he's in the wrong here, regardless of circumstance. Someone used charity as an example - if I gave my wages to Cancer Research UK this month, then realised I couldn't pay my rent, would I be entitled to ask for it back?
If he absolutely must ask for the games back, he should email the guys individually instead of guilting them in public. Again, sorry if I sound harsh but seriously, I'm right. You chaps who disagree obviously know the OP on a more personal level and I don't blame you for sticking up for him, but really, take a look at it from a non-personal perspective.
If the OP had sent me a game and asked for it back, I probably would send it back. Not because I'd feel guilty, but because I'm a nice guy. Although I'd be perfectly within my rights to keep it.
