It wouldn't be unheard of, although I have been bit by buying consoles for extended family and friends in the past.
On two seperate occasions I have bought a console for someone, just for them to turn around and sell it, or give it to someone else.
Worst was one of my consins. I went over for a family event, and her parents were like everyone should check out her room, she re-painted it, and decorated it herself. She was around 15 at the time. Not only had I bought her a PS3, but I also gave her my SXRD when I bought my 1st 3D TV. I go in the room and there is a Vizio LCD and a Comcast Box, and nothing else. I was like "oh, you got a new TV". She is like, yeah, I sold the PS3 and TV, that is how I was able to make over my room".
The other time I bought a PS4 for a friend at work, because they wanted to play MLB The Show. They ended up Switching Jobs within the company, and a few weeks later they stopped being on PSN. After a few more weeks, I ran into them as they came back to the site I work at to get some certifications. I was like, "hey, I never see you on PSN anymore". The dude comes back, with, "Yeah, I gave the PS4 to my Girl".
I'm not against buying stuff for people, even people I don't know, but I am more cautious now than I was when I was younger. If it is within my means though, I love helping people out, and giving more people the oppertuinty to game.
A $500 console is a pretty tall order for someone I only know from a profile on a gaming site. Right now, I would have to say it is unlikley.
That's pretty incredible. and good on you for wanting to be generous with ppl you know. Sucks that some ppl didn't seem to care too much about the gift but I suppose since it is theirs they can do with it as they wish. but yeah, I guess the disappointment.
Though regardless of your financial situation , I do hope the PS5 is not overly expensive! Seems like you are going to be spending quite a bit!
