I am sorry, but you have completely missed my point. All software has bugs, period. With games, you can omit assertions so that these bugs cause glitches in the game (or cause no visible change at all), or you can keep them in, slowing down the engine because of numerous runtime checks and crashing the whole game if a single bug occurs. That's way more sloppy design than the former.
