For example, imagine playing a racing game and all of the sudden you must play Tetris to continue...
Well something like that happened while playing Snatcher, I made it to the final part of the game only to be stumped by an action sequence!
I had to shoot down countless enemies, and after playing for hours, I finally beat them just to be killed in the next sequence, and brought to the beginning again!
After countless hours of gaming I gave up, besides my thumbs were huritng anyway, but knowing I couldn't beat an adventure becuase of the action sequence really but me off...
The game experience was just perfect until then...
