Rayman 1 Ok its not hard anymore but when i was kid i had trouble to find all cages some cages were hidden secretly and will appear only when you touch secret spot Wtf? Also Crash 1 with horrible slippery controls you have complete the whole stage without dieng and collect all boxes=RAGE!
Yup, Rayman & Crash Bandicoot got incredibly hard midway through. The save systems were not ideal... I also had a hard time trying to beat Destruction Derby 2 ( it turns out the Wrecking Racing mode could only be beat by lurking around and careening into your opponents (as opposed to actually racing). The standard race mode in the game was completely impossible to win.
If a tree falls in a forest and you hear it, but your eyes are closed, how do you know it's not just fifty porcupines sliding down a hill?
