Probably a controversial opinion, but I think this game is as much fun and is as quality as New Vegas. Just in a completely different way. New Vegas shines with player-reactive elements and plot, 4 shines with exploration and customization. Both games allow you to play your way, just with different focus on HOW players will do so. And both games have amazing robot characters.
Speaking of robot characters...

I, too, have a game on Steam called Clash: Robot Detective. https://store.steampowered.com/app/2222480/Clash_Robot_Detective__Complete_Edition/
