I am wondering if it is fair to ask you to name that game. I'm not sure if you have ever played it but it has around 7,000,000 players and it is a strategy game. The first word in the title is Forge and if you do not get this I will consider your last reply as the correct answer instead.
Mystic I am very shocked about those reviews but this game is not a shoot'em up. This game is a start as a caveman city on Earth and reach a futuristic city on mars through all eras in between kind of game. Very educational too. Think of it like a sim city where you build something like a theme park.
