One fateful day a group of game developers thought "hey wouldnt it be cool if there was a simple plane building game" and that team was ... JUNDROO then they made a game and thought to themselves "hugh what shall we call this?" then gerald said "how about complicated planes!" "no gerald thats dumb maybe we will call it simple planes!"
the end
I'm not exactly sure who Gerald is tho...
Nah. The story actually goes like this.
One up on a time there were 3 prankster gangsters who made a game called simple wheels, who sold it as an April 1st joke, paying people to rate it 5 stars. Then one said "Hey I know! Why don't we make this game into Simple Planes?" And so they did. The end.
