Steal my idea, I don't care. It's not like I'll make the game, anyways.
Game Name: Everything is Inevitable
Story: Your character is a militia soldier who hears about a threat to the world. Setting out to save the world with several close comrades of his, including a female scout, a hacker, and an infiltrator, you track down various leads, figuring out which ones, if any, pan out. Eventually, you find out that one person is behind the threat, and track him down. However, just as you reach that person, she sets her plan into motion, taking over the world. With that, the game ends.
Gameplay: It plays as a real-time WRPG. You go into various towns, looking for leads to follow, and then try to figure which of your leads actually goes anywhere. There is no real morality system, but based on how you get leads and ask questions, the game will alter future reactions accordingly. There is also a character creation system, in which you design a character like in Soul Calibur 3. However, you then decide which weapon or weapons your character is qualified to use, and while you can learn to use more weapons later on, you will need to train with other weapons in order to use them, if they are a different type of weapon. For example, if you have a character skilled in rapiers and long blades, then pick up a broadsword, you will have to train to use the broadsword effectively. Each weapon will also have different motions and stances. For example, a rapier or similar longsword will have more of a light-footed, darting motion as an attack, while broadswords have more of a wide arc in a shorter range.
Rating: M for mature, due to blood, violence, and scenes of torture (as one of the more extreme options open to you while following up leads)
