Do we really need _input(event) for simple games?

Hi, I am new here. I am trying to make a simple game like Fire Emblem series (full 2D), with just 3 buttons (mouse click, accept, cancel). I have followed some game tutorials, and none of them uses input(event) function, they simply use if Input.is_action_pressed('key'). So is input(event) really necessary? Thanks!

It just depends on what you want to do. Using input events will save a tiny bit on performance as opposed to checking is_action_pressed() every frame. But you're probably only using input for a few objects anyway, so that would be negligible. You can run into some issues with pausing if you're using pressed and released events; if you press a key, then pause it, then release the key, the paused objects won't get the released event. On the other hand events are nice since they just happen once. Checking is_action_pressed won't tell you when the key got pressed or released (unless you store the value and check it each time, etc.). So it just depends on your situation.
