Let me put it for you in another way:
If you use your amiga exclusively for games, and dont give a damn about what kickstart or OS does it run, as long as you insert a floppy, turn the power on and then play, and that is about all you do with it. Then, if that is the case, this type of kickstart rom update is useless.
An Amiga is much more than a gaming console, dont you think so?
