Hello, Happy here! I am in middle of developing new content for Adventure Ace, so we can release a full version of the game for this event here, which ends 1st of July: http://rpgmaker.net/events/nagademo/
The demo version of Adventure Ace had roughly 50 missions for 2 in-game months, so in order to cover the remaining 10 in-game months I have my hands quite full of work developing new missions and treasures for you to discover!
And even though internet provides most of the information I need, I have found library quite useful source as well, having all the sorts of relevant information gathered within a few book covers.
It's good to get at least some of your references right!
Anyway, here's your chance to become part of the Adventure Ace team! Because we need testers! The game will approximately last for 2 hours, or so. The testing Starts around 24th of June or so, though all content might not be in yet by then, but at least there should be enough stuff for you to test out by then. The testing ends around 27th or so, so you will have 4 days!
Just reply here or PM me if you want to help us out.
