Wow, people got tensed up with Croc's Lair? Honestly surprises me.
Don't you know you can easily knock him away with like two buttons?(lock-on, throw batarang). Seems obvious after the first time you do it. Then it just becomes a really slow march to the entrance. Almost a parody given the big disparity between music effect and reality. Probably the worst part in the game, closely followed by the final boss.

The original Donkey Kong uses a joystick and one button. You can pretty much just move left and right, climb ladders, and jump. It's about as simplistic as games get.
Yet 30 years later, people are still playing the game, fighting for the high score.
Complexity is not the same thing as depth.
Depth only comes from complexity though. The reason apparently simpler games can be more fun is that they can be more elegant. Elegance means more refinement so you get games which rules don't trip over themselves and can lead to unbalanced boring games or fine games with harmful aspects littered throughout. For example JRPGs and WRPGs can be wildly complex, but very few are interesting strategic challenges(and less so than vanilla strategy games even then). Also at the end of the day a refined concept is always entertaining for at least awhile, even if it has been replaced by slightly less refined, but overall better games.
That aside Donkey Kong is pretty fucking boring to what we have today unless you are playing it at the highest level. EDIT: I am being needlessly harsh, lol. Simply, its appeal wears very thin if you've experienced gaming of today and recent yesterday(Super Mario Bros will do). If you don't make such an unfair comparison, it is an amazing game.
Arkham Asylum's combat system is both simplistic(this applies both to what it physically demands and the tools you are given) and unrefined(overpowered techniques piled upon overpowered techniques). At its highest level(the very strict challenge rooms) it is still less fun than fucking around in more competent games.
EDIT: I will say this though: Something about AA's battle system is extremely seductive. I think it might be the speedy/automatic pace of attacking(gets to people to call it "rhythmic" lol) and aesthetic appearance(which is satisfying to look at) and the general ease of the game probably didn't hurt. Shallow, but charming.
