What if you're 60, and stopped playing when the Super Nintendo stopped being the most popular machine? I enjoyed the old Infocom text games and the Myst series. I hate the 1st person shooter type of games like "Call of Duty" whatever. I think the old adventure games are some of the best. I go to Target and look at the PC games available. Nothing even looks good. I think the last game I bought was some sort of adventure type of game, but it turned out to be a real bore after a few minutes. Oh well. Back to the fridge for another beer.
Get a tablet. It is casual and short gaming sessions at its finest. There are free game apps that will keep you occupied for months. Not to mention lots of decent games that only cost a few bucks.
