Now the reason for this post is that on the forums for the competition, one of the entrants has posted a MONSTER set of links to FREE game resources. Everything from game engines(and source) to sound and art resources.
Have a gander HERE, and gab what you need!!
There are a load of other resources for the noob and experienced alike including Game Programming Beginners Guide and How do I make games? A Path to Game Development, both articles are very good, they are a few years old now but still worth a read as the concepts are still sound.
