Aran, you should phrase things more constructively and think of better ways to help than just "look at all the other better games than yours on the forums and make yours better!". While this can work, it's not the only way to improve. A good way is to ask yourself a lot of questions about your original ideas. For example, what happened to him while he was roaming the streets? How did he manage to go from a five year old roaming the streets to a man in an army. There must be some more story there. Also ask questions about the characters, what was the motivation of the man who killed his parents? How did he then become the main criminal of the war etc.
If you keep asking these kinds of questions you will be inspired (hopefully) into answers that enrich your story, without anything from the outside coming in and affecting it. It makes it more original to just come from your head. Also, once you have good characters and you know them well enough, they can sometimes affect the outcome of the story. If you think "I want the story to do this" but then realise "that's not what this character would do at all!" you'll have a new interesting direction for the plot to go down.
Good luck.
