Nirth: It seems people never really ask this question seriously but I'm going to answer seriously anyway because others will take care of the going joke..
Other than finding a way to not need working, cut down on social life and sleep, chances are you are not going to get that much more time, it's about priority, picking important games first and leave out the mediocre ones last, preferably skipping them altogether.
I want to play Witcher 3 but I'm afraid. I'm afraid I will loose my
SOUL!. Seriously though that game can be played forever.
tritone: For the right price, Total Recall(tm) will implant the memories of having played any game(s) you want. Just don't forget to record a video of yourself, to remind yourself of who your friends, family, girlfriends, wife, etc. are and have it mailed to your house before you visit TR so you'll watch it later when it arrives in the mail. You know, in case they decide to give you some "free" memories you didn't want. Or take away some you wanted to keep.
Ooooh I like this idea. Buuuut what if I WANT to forget about my friends and family. Does that cost extra?
