Green Monster Games is a startup founded by an interesting combination of people which includes Boston Red Sox pitcher Curt Schilling, the creator the the comic book Spawn, Todd McFarlane and sci-fi writer, R.A. Salvatore. With this all-star cast of founders it appears they are hiring programmers to actually develop the product.
GMG is looking to change the landscape of online gaming. It is not totally clear what type of games they are looking to create but I think it would be safe to assume that it is going to be some sort of epic journey looking to engage players for hours and hours (i.e. Second Life or World of Warcraft).
