I'm still (master)debating with myself about what I'm going to do. =(
On the one hand, having a PS4 would be awesome. I could play "inFamous: Second Son" when it comes out next month.
On the other hand, I don't know of any other games coming out this year I'm dying to play. There's the new Transformers game, but I still have to play the two previous ones on PS3. I have an extensive library, both already purchased and intended to be at some point, to play for this console generation. Had I not won a next gen system for free, I wouldn't have considered buying one for years.
"Uncharted 4" probably isn't coming out before next year anyway, and who knows when KHIII and FFXV are coming (if at all in the latter's case). If I get the PS4, chances are I'm going to play the hell out of Second Son and then not buy another PS4 game for at least a year.
And there's also the fact I could buy groceries for months with this gift card.
What I may do is treat myself to a game like "The Last of Us" and a nice steak dinner for me and my girlfriend, then spend the rest on groceries/whatever I feel like over the next few months.
I'm not used to having disposable money. This is such a difficult situation to be in. XD
