(I know a thread similar to this has been created, but it was for DS, and never took off.)

Simple. Make up an original or unoriginal game title for any platform. Can be any sort you want. Would be nice if there was a paragraph to describe it. Include as much or as little detail as you like. You can even go so far as to make a cover for it.

Big Brother: Police State
(Real-Time Strategy)

A game based on George Orwell's 1984. You take the role of the omnipresent, all-powerful Big Brother, with the aim of destroying ALL opposition, ALL possibility of opposition, ALL free thought, and waging endless war against rival superpowers. If you can destroy liberty before liberty destroys you, you win. Use a huge arsenal of weapons, propaganda, torture methods, terror tactics, and surveillance technology to wage war on thought criminals. Being an evil dictator has never been more fun.

Rated A for AWESOME.

Dragon Emblems
(RPG)

When I was younger I thought about making a game with this title, basically the Heros village gets attacked by a red dragon with two heads. Stripped of everything the Hero must venture to get revenge! Basically for every Dragon Boss you kill they drop a Dragon Emblem, which is of great significane in the near end. If somebody steals this idea, and makes a game out of it, I will open a can of Boricua Whoop-Ass on them.

Then again the idea isn't very good XD.

War Piece (LOL PUN)

Real-time strategy games edged strongly towards combat realism and tactics, yet well-paced battles. Based on a strong storyline, even more than Command & Conquer, alongside a more freestyle world campaign mode, and of course, multiplayer. There are various factions to play with, which have different units, different battle strategies, and so on.
Realism means that weapons are not 100% accurate, and hit points and damage are actually realistic. For instance, one direct hit from your RPG-7 should destroy a light vehicle, and there would be realistic splash damage. The battlefield is highly interactive. Civilians and civilian settlements are used for various purposes, and have strategic importance.
Ammunition, oil, rations, morale, and energy are essential battlefield resources, which you both have to collect and distribute to groups of soldiers, via trucks, helicopters, etc. Forces need ammunition to fight, and it is supplied at drop zones, and by ammo factories; no oil means petrol/diesel/whatever generators stop running, and vehicles cannot run - oil is produced by oil plants(when you control them) and tanker depots. Ration supplies affect the performance of soldiers, and prolonged starvation will gradually kill off forces.
Morale affects the performance of soldiers and civilian support or resistance, and is related to various factors. Actions and combat performance are important deciding points, and morality also comes into play. Commit bad acts, and morale will decrease, and so on. It is affected by all other resources.
Energy is pretty simple, and is used to keep automated defences and base systems operational.
Money is collected by controlling strategic points, resources and civic buildings(which have special bonuses), and a steady supply flows through anyway. Used to purchase units, upgrades, and research.
Rations, oil, energy, and ammunition effectively act as flexible unit caps, and also force the player to rationalise their operations.

There is a generous range of carefully balanced, yet realistic units. Marksmen (Snipers) kill from long distances, can pierce armour, yet take a long time to reload, and give away their positions when they are shooting, and are also comparatively expensive. Scout (Snipers) have a quicker rate of fire, don't give away their positions when shooting, yet have a somewhat shorter range, and cannot pierce armoured vehicles.

First game is set in 2015, when tensions are getting really hot. Full-scale war doesn't start immediately, and the war escalates into a world war from the first few missions in the storyline. Epic.

The General (RTS/RPG)

You control a general in medieval times, the dark ages, if you will. You have recently fallen from power, and you command no soldiers. And you're a hunted man.

As a general, you must rise up in power, gaining commoners to utilize as your soldiers, commanding them as your army, gaining money to buy equipment for your soldiers, hiring mercenaries and buying siege engines to take over castles, and becoming the general you once were.

You do this by means of an ingenious control system that allows you to freely attack and shout orders at the same time. The more soldiers you have, the more powerful you become. With a castle, you can hire craftsmen that do everything from healing your men to craft new armour types to shine your boots so well that looking at them hurts your eyes.

You also have other "duties" to accomplish, such as find a wife, have children, and work with the local factions. In total, you must live a life of war, blood and, strangely, leisure.

I'd buy a Wii just for that.

XD

Shame there aren't too many adult-orientated games.
