One of the least surprising games I've played is Rick Dangerous. It is also the absolutely not Indiana Jones in all aspects. The original Indiana Jones game was crap, and this is how it should've been done, but this game does not have the quality of the Indiana universe.
This is a quite ordinary platformer. They were pretty much produced like FPS are today, copy paste and change the graphics/story a little bit.
I did enjoy the game when I was small, but it didn't really stand the test of time, and I don't think I will go for a replay.
