In dead space, I never used that thing that slow down time to anything other than pass some obstacles. I finished the game that way. It was kinda infuriating i had so much of those that i would never use, but was always lacking amunition and oxygen. Later, i saw a gameplay where someone used that item on enemies too, making way easier to take down the tougher enemies of the game. But you know what? I enjoyed the game more that way, it was way more tense.
Also had no idea you could ster in fzero(or mario kart) with the shoulder buttons. Never finished because of it.
In top gear, a racing game, my friend and i would win races and in the end, upgrade our cars parts to keep up with the competition. However, at some point of the game, Our cars were running out of gas before the end of the race, and we keep getting game over after game over, no idea why. Then, we realize our mistake: of all mparts we were upgrading, we never upgrade our gearbox, because we had no idea what was and saw no improvment in spending money upgrading it (we also didn't speak english, so we were clueless on what that word even meant). After finally investing on that, we stoped having a gas problem.
I'm sure am forggeting another one, but thats all i can remeber out of the top of my head.
Just remenbered: in zelda wind waker, i had no idea what bait was for. So i got as far as the triforce quest without barely any maps!
"Hardware design isn’t about making the most powerful thing you can.
Today most hardware design is left to other companies, but when you make hardware without taking into account the needs of the eventual software developers, you end up with bloated hardware full of pointless excess. From the outset one must consider design from both a hardware and software perspective."
