Since you don't want to buy a PS4, I have a rather simple solution for you:
Buy 3DS
Sell 3DS and buy Vita
Sell Vita and buy PS3
Sell PS3 and buy Wii U
Sell Wii U and buy Xbox One
Sell Xbox One and buy Infamous Second Son
Go into Gamestop, break open the display case, put your Infamous disk in display PS4. Play until you get kicked out. Ask for your Infamous disk back. Sell Infamous and buy a 3DS. Repeat.
