how games have changed.....

To echo some of the other posts in this thread: that's a very big question. At the very least, video games have come a long way from their particularly humble beginnings. For better or for worse, they've entered the public consciousness as something very different from the nerd hobby from previous decades (as well as the stigma attached).

With the rise of smartphones, gaming is more accessible than it's ever been. Whether that's a good thing, considering the market for these games (which often are hyper-casual, stuffed to the brim with microtransactions), is a whole other question entirely.
