Retro game idea's needed, Yes, idea's as in more than one

Retro Games : Arcade Hits ( Or RGAH ) is my current project which is full of differen't arcade styled games that are completely original.
What I need is an idea - or idea's for differen't games.

Right now -

1. In an underground cave, you play as a man who must explore the cave dodging monsters. To earn points you must pick up rocks and bring them back to the beggining of the cave. Depending on the color of the rock you'll get a certain amount of points. You can defeat enemies by picking up a rock and throwing it at them, but if the rock falls to far down or is thrown to many times it will break.

2. When you finally get out of the cave, a dragon comes and eats you. You then play as the dragon in a contra-style minigame.

What I mean to say was that I need idea's for completely seperate games.
You know, like you select a game at the beggining and play that, then once you lose you select again?
They're supposed to be simple, with a simple goal and as you progress it gets harder until you lose.

2. you are a plumber who goes around through pipes, stomps turtles and eats mushrooms
2. you are a little guy who lives in a computer and zaps viruses whilst dodging firewalls (reminiscent of the flamethrowers in SMB3 doomships) and spyware (like the turrets in portal but rotating their turret and with lasers)... If you say no then I'll make it 'cause this idea is awesome.
