Everyone likes collecting things. We see that with the licenses. So why not make collectibles for the normal RP sections? I'm thinking about something like exploration badges.
These could be simple images with recolors, just like the licenses. One set for Lambastia and one for Barakka. And - I'm not sure what's better - they could either be tied to a pet or to the user. Or maybe there could be badges for both?
Example (pet-tied):
Billy is exploring the Lambastia World Bridge. Just like that. After spending a certain amount of time there (X posts), no matter what he does there, he is considered to know his way around the area well enough and he gets an explorer badge. Billy then decides to join a hunt for a wild pet in Terrace park. He again spends a lot of time there and after a certain amount of posts is allowed to take the badge of that area as well. Billy goes to Nori Volcano, but only for 10 posts. That's not enough for the badge! But six months later, he comes back for a second adventure and with both combined, he has enough posts to claim another badge. He then goes to the other sections of Lambastia, explores them all to get all his badges and then
So basically, a pet needs to spend X posts (which can be the same amount for each area or different amounts for each - more for the bigger ones, less for the smaller ones) in a region to claim a badge. The posts can be spread over several RPs. User-made events, hunts, normal RPs, it doesn't matter. The badge can come with a small KS prize. For exploring all areas of a continent, there's a bigger prize and a shiny badge. And if a pet explores both continents, there could be a special badge with a big prize.
Since it would be pet-tied, it could be something like a free add-on for the pet. Or even a breeding room key, since even just 20 posts in every area means several hundred posts with just one pet for the big prize.
If it's user-tied, the post number requirements would need to be higher since it would be shared between all pets and RPs. However, that would also require a user to take count of all their RP posts and a lot of users already don't do that for stats, so that seems like too much of a hassle. Doing it for a single explorer pet sounds just more doable to me.
I dunno. Just an idea because I'm OCD and like collecting stuff I guess? This is basically a long-time thing, just like the breeding licenses, nothing someone is supposed to finish in a week.
