This is fun for an afternoon. It's fun to invent your own games, and see your company grow etc, but let's be honest here, there isn't much replayability or very profound gameplay here. It's enjoyable on a first run, because of an enjoyable UI, a satisfying gameplay loop, with dumb spikes of joy when you see your game become a hit. It's also an hommage to the history of gaming, and in that sense it's pretty cool. This is far from a classic, but far from a bad time too.
