Well, I was bored, so I wrote a couple of things that I hate to see in games.

Boring, easy games:

In a maze game, make things to KILL the player. In a platform games, make enemies. No, not those stupid zombies walking back and forth waiting to get killed. I mean an enemy that can jump or shoot. This is mainly because of laziness that lame enemies are created. Sure, include one or two dumb enemies at the beginning. But the game should get harder as you progress.

Nonexistent Threats:

Oh no! You are trapped inside a spaceship that is headed for the sun! Reach the escape hatch before it’s too late! But wait…there is no time limit to the level…so what’s the point of having a threat? Many games have done this and it’s mainly because they’re too lazy to add a timer.
