I have played both back in the day and enjoy them as well. Now if only these were made to work for the iPad. As a developer Mr. Jones, this would be a product I would pay for, though rights to development might be a challenge. Metal Slug and Max Payne, as apposed to Gravity Guy and Burger time, have more going on in terms of player actions and moves. I tend to enjoy games that have greater variety in actions, a good example would be an old game I used to play in school, Treasure Mountain! and Treasure MathStorm! by the Learning Company. Educational games have always struck me as fun. I suggest checking it out. I would like to know what you both think!
Thanks
