Help me decide!

I have two ideas for stories and was wondering if everyone could tell me which one was better. The first is a game set in 1939. When Indiana Jones is kidknapped by Nazis during an expedition to discover the fate of Atlantis, six of his greatest students recieve parts of a map in the post. It is the beginning of an adventure which will see them exploring the world, facing death traps and discovering an ancient machine with the power to destroy everything as they try to rescue their tutor.... The second is based on the XXX films in which a group of ex cons are recruited by the NSA to infilitrate a terrorist organisation planning on releasing their imprisoned leader by any means possible. This one would feature lots of car chases and spectacular stunts in the same style as the movies.
