Unity's asset import system: where time goes to die. You've got a SampleScene, a PlayerController, and approximately 2 hours and 27 minutes of your life being consumed by a progress bar that's moving slower than a bubble sort on a potato. The "Importing assets" dialog is basically Unity's way of saying "go grab coffee, walk your dog, maybe learn a new language while you're at it." The rage is real. Unity's notorious import times have driven many developers to consider alternatives like Godot, which is known for its lightning-fast startup and asset handling. When your game engine spends more time importing than you spend actually developing, the grass starts looking pretty green on the other side of the fence. Fun fact: Unity reimports assets every time it detects changes or when you first open a project, and with larger projects, this can legitimately take hours. It's like waiting for Windows Update, except you actually need to work.
