While we here at Gadgets are guilty of having stacks and stacks of PC games in our closets collecting dust, we don’t even come in the same league as PlayStation collecting’s community member Ahans76. He has every single NTSC PS2 game ever made, in mint condition and still sealed in its original box. His collection of 1800 PS2 games is probably the only one in the world today, and all the games in his PS2 collection are all first run and limited editions, meaning no second editions or re-releases. Coming up with the monetary value of his whole collection is difficult, but it’s probably safe to say it’s in the thousands of dollars.
