You know I really must ask, why are things like this not being posted in the very active and very directly related community site,
Pascal Game Development?
If you want maximum exposure for this even PGD is the place to post about it. There are many users that use Lazarus and make games, very nice games in fact, with it. You would do well to advertise such events on our site. In fact we don't mind, we love to hear about these types of events.
I've made a new post about it on our new site's front page, feel free to come read and talk with all the game developers should they require more information about the contest. Personally I think everyone is itching for a new competition.
