This is a fanfiction I worked VERY hard on back when I was posting regularly in the Sega forums. It was an idea I had for a war type video game set in the Sonic universe. Not a Real Time Strategy type though, rather a 3rd person shooter, where you have different squads set in different areas of a map, each squad lead by a playable Squad Leader, which you would control and navigate your squad on the map. You would switch which squad you were playing as by bringing up a menu that shows the map and where each squad was set, select the squad and begin playing as the selected squad. The squads you weren't playing as at the time would hold their position and defend themselves until you moved them yourself, or use the map menu to give a specific point for them to advance to while you where playing as a different squad.
I wanted the characters you play as to be fighting for good, but I still wanted it to be Robotnik and his Eggman Army rather than the G.U.N. military force, so this is the fan fiction that came of it. Ill be posting it in bits and pieces, to make it easier to follow seeing as its such a long read. Enjoy.
