Some games maybe had not-worked-out ideas, released pre-maturely.
It's something to keep in mind.
Or what about newer games. Playable most of the time, but with incredible bad design-ideas now and then?
Like in Turok, for Xbox360. Looks and plays ok (unreal engine 3), only 1 area has neverending flying bugs, which you have to ignore, to place bombs.
The ignoring part is too difficult, as the character can't evade well enough, nor runs fast enough.
Finishing this dull area requires luck and many tries.
Turok (from Propaganda Games) is my most hated game.
