Video game technology has come such a long way that folks don't recognize our oldie but goodie games. In terms of pixels and visuals there's no competition, but Pac Man was groundbreaking for it's time and still has plenty of fans. There's a reason why classic NES consoles are so hot now. There are good games now, like the Uncharted series, and the MLB, NHL, and FIFA titles, but how people play and how they experience them is so different.
The video gaming industry is full of wonderful games today. Yes, Pac-Man started it all. Of course we owe a lot of respect to the Father of Pac-man. However, this does not mean that none of the video games today are no good. There are countless popular video game franchises.
No, there are not good video games today, because they are too complicated and they are not easy enough to understand. Two-dimensional video games were easy enough to process for most people. Also, in the old days, when you lost in a video game, you lost. Today it seems like you have unlimited life.
Pac-Man was new and interesting. it was something no one had really seen, up to that point. Video games are becoming boring. They are all the same now. They are "cookie-cutter" games with only small differences. Character is given a quest. Character has tools for quest. Character must go through different levels to achieve quest. Character must fight their way through each level. Character eventually achieves quest. They might be fantasy or military or zombies, but they are all basically the same.
