Like Tom said, 100 events can actually do quite a bit. But if you are serious about game development, $100 for a personal license isn't really that much in the long term.
While I was playing around with C2 using the free version most of the prototypes I made rarely needed more then 100 events. The reason I ended up buying the full version was actually for the Families feature which allows you much more freedom to make games with even less events.
