Bit of a late reply, but on those emotionally draining people, ask what you get from them. If you aren't satisfied with what you're getting related to what you're giving them, either be honest about that with them, see if that can change, or end the relationship.
Remember if that you feel you owe them something, then why shouldn't they owe you as well? Why does it only apply to you? The only people who deserve that sort of faithfulness are the people who'll be thinking the exact same way as you, not the people who are more than willing to leech off the goodwill and kindness of others.
Like the actual game play and audio? I don't think so, I didn't save a copy either. Might still be on our xboxs if that was in the last few games we played. The only thing I think you can get from it is the stats recorded somewhere on whereever they are keeping Halo 4 these days.
his father has requested people to post things on his wall, it comforts him a bit. i did it without knowing, didn't need to be asked really, but for those of you that didn't know or hadn't written anything, we should lend his dad a hand
