What was Return to Castle Wolfenstein like?
Cake. A delicious, fragile cake. If handled carefully, it would stay firm until it entered your mouth, so that you may savor the most of it. Rushing it would make the damn thing crumble, and half of it would be left all over the place, so you would spend to much time picking up the pieces to be able to enjoy it.
Err, well that's sort of the gist of it. You're put alone, against rather high amounts of opposing enemies, making the game a bit challenging, and charging head on rather unpractical in some cases. Very fun game though. The way the levels are designed I've seen in no game after, but some games before (most of them by id as well).
