The style and atmosphere of this game are more similar to UEBS or TABS than to traditional RTS games. Many modern RTS games use a simpler style, making it easier to see enemies, buildings, and other stuff.
Anyway this game is huge. It's almost impossible to create a flawless game of this scale in just 4 days, which, with the fact that it doesn't really fit the theme, makes me lowkey think its a pre-built game.
