I have four Steam gaming accounts. There are many games on Steam that are just there to appeal to your memories from your early days of gaming. I own just about every game worthy of being played including some that have stopped working (EA Sports mostly) since technology has progressed.
I own every simulation I could find, including many that are so broken they don't really simulate anything more than frustration. I have considered buying out the titles just to make something playable, but then I think that the money spent would never be recovered.
One of my squad members looked into my library and commented that I could never find the time to play them all. He's right about that, probably, but I also have six kids now, and a seventh on the way. My kids will love many of these games. I bought the games mostly to see how games are designed, how they function, and what is working in the gaming world. I play games just three times a week for youtube, and a fourth night for time with the wife. I also paint with Photoshop (for fun), and create sounds a music with programs I found on Steam. Steam is also a really good place to get downloads like Blender, and GameMaker Studio (really easy to use too).
We are putting up a dairy on the family property, so my free time will be decreasing and we may move to the PI very soon depending on the cultural climate here.
I don't feel any ill effects from playing computer games, but we did study how to 'cure' some of the problems that come up and I believe most gaming companies will be making those changes as time goes on. Technology is a wonderful thing, as long as you remember not to back toward the cliff's edge when taking your selfies.
