I had an interesting idea for a game but little time or desire to make it, so I thought I’d throw it on the forum and let someone else have at it. If you have ideas for good games that you don’t intend on keeping for yourself, go ahead and post 'em.
After several straight hours of Fieldrunners I started analyzing the tower defense trend that has been sweeping the internet for the last couple years. I’ve seen dozens of clones that change nothing but the graphics and minor details. Nothing that really revolutionizes gameplay. Then I got to thinking. Why do you always control the towers and never the runners? A game where you start off in the barracks and buy units to rush through a predetermined field of towers could be a whole lot of fun. Put the player on the other side of that battle. Tower Siege instead of Tower Defense.
