I know I'm 17 years too late but would it be possible to create a football game in the same style as Tennis Elbow, with a focus on perfect ball physics and pure gameplay, rather than graphics and presentation? How much more difficult would you expect this kind of project to be compared to a tennis game? If you was making it in theory, how would go about it?
Cheers, mate — I love everything you do. You're a master of your craft.
