i went to my local institute of technology yesterday to learn to make games... we used this software
http://byob.berkeley.edu/ it is a scratch based program that allows you to make basic games... you do need some knowledge on game physics to make anything... i can send people a game that i spent about 20 minutes making... it can only be played through BYOB at the moment...
well anyway... if you think you can make games then try out the software
