1. a "Skatepark" area for the adolescent Sylesti - a place to put adolescent Sylesti so that the hatchery only shows egglings and hatchlings :;: allows you to put equipment on them, send them on quests, etc. :;: won't allow you to put them in your party
2. a dorm/home for the player to customize, etc.
this will be added on to at a later date (if I can think of anything)
edit: the dorm was just because of me wondering where the player's stables are

1. you can just. Send adolescent sylesti to your stables to they aren't in your hatchery? And so long as they're in your stables, you can do everything with them that you can do with a regular adult except breed them? (if you couldn't, you'd be a bit screwed at the start of the game, since starters spend their first 18 days as adolescents)

2. but why? for what purpose?

1. Just move it to your stables?...

2. Seems like a waste of coding for no good reason

the adolescent area is for if there isn't enough space for them in the stable(s)

If there isn't space, then make space.
Either earn money or release, stable space is something you would have to work on.

this just my opinion/suggestion, your entitled to your own

I'd have to say no support to either of these.

It's already a nicety that the adolescents are able to spend an extra 18 days in the hatchery, not taking up space in stables. There is no need for another, separate, 'free' space for adolescents. If you only want hatchlings and egglings in the hatchery, the option is there to manually move adolescents to the stable. If you do not have room in the stable, then you need to make room as they are going to go there eventually.

For the player housing... I don't see the need? It seems like something that would take a lot of time to code, implement, and offer upgrades for, for something that really serves no purpose. I'm also not sure what you mean by your edit about this being used to find players' stables? I mean, you click the players' usernames, then click 'view stables' and there they are.

1: We don't need separate spaces. But, if there was some sort of button to see only hatchlings, only egglings, only adolescents, or something like that (which doesn't remove them, just temporarily hides those who don't fit the description), that might be useful.
2: Not sure why that would be needed.
