Do you think it is worth selling PS2 games? I barely play them but i dont know.. they will only be worth less and less right... What do you think worth selling them?
If you haven't touched a game in 5 months or more and you want to sell it. Do it,
BTW I would sell them as a lot on ebay (all the games) you will get more then selling them 1 by 1.
Also what games do you have?
No video game ever holds it's value unless it's a collector's edition, it's rare, or if the game is widely considered as one of the best games ever.
Your best bet is to sell them now before they become even more worthless.
