"Retro video games" is a broad term, anything from the early Atari 2600 stuff to the PS2 3D games era can fall into this category. The OP's image may have a point, but it was made by a sophist.

>What do you think about efforts to recreate earlier eras of gaming?
I think that people who make new games for the old platforms (NES, SNES, C-64, you name it) are doing it right. That's the only legit way to "recreate earlier eras of gaming". It is cool to see how people are incorporating new-skool game design/approach to the old-skool platforms.

An average Unity-based game with a pseudo pixel-art graphics is another thing, though. These I don't care about. These games are not genuine, and a typical example of an cargo cult.
