Hello,

I've been playing this game since 2011, and I've accumulated a lot of ideas and wishes for it, that I will list in more or less details below :D
I could make 10 posts, or maybe 20, but I figured it's better to not flood and instead keep it contained to one spot.

All ideas below may vary in craziness too, nothing is off the table when it comes to ideas, even if I try to think of the consequences of all things I suggest!
Note that I may also update this post in the future to include even more, Ideas never run out either :D

Cosmetics and Prize boxes

• Trader that sells old costumes, bound upon buying (1+ year old, and if they've not been in a promotion or depot sale for minimum 3 months)
• Recipes for costume items, such as Raiments, Flak Jackets, Draped Armors, Brigandine, Cloaks, Hoods, Culets, etc (basically all proto reskins, but maybe more too!). This could significantly increase the value of all items that don't use these models, due to those being uncraftable. The recipes could also create bound by default costumes however, making acquiring new items more interesting than trying to find duplicates of the items you already have.
• Plainly Re-Running boxes that are 10 years and older is also an option! Some of my favorites include the Costruct Prize box, Volcanic Prize box, all of the Gem (Peridot, Citrine, Ruby...), The Blooming Prize Box, and some more. Many of those items have gone too rare, and are dearly missed by many :(
• A Prize Box Calendar for the depot, that re-runs older boxes every couple weeks, so that none of the older items get too expensive or rare (thiniking of the gem colors, volcanic items, Autumn items, Lovely items, and all of those 10+ years old things)
• In game screen informing players about drop rates in prize boxes, so we don't have to navigate the (quite slow, but beloved) Wiki just to have a vague idea of how often some of these items will drop (or more realisticaly, when is it that we might get the one we want)
• A way to preview outfits with items we don't have in game, maybe as a secondary screen or menu on Bechamel? Where he'd present you with a list of all items in game, with a color variant selector, and accessory options too, kind like the knight creator but as a more visual UI.

Risk, reward, and Fairness

• More rewards for "very difficult"/Danger levels, such as Danger rooms, Danger Missions, Shadow Lairs, Treasure vaults... The current loot rewards for those kind of fail to make me feel like these are worth it, if anything the loot from ALL of FSC combined is more attractive than the loot from, say, Heart of Ice.
• In-game probabilities for rarity items, so that players aren't left in complete darkness about how rare these are
• More Biased Randomness for some progression-important Rarity drops, such as Crystals, or Orbs, so that if a player hasn't had any in a long while, their chances increase by a lot. (let's be real, the "economy" around these things is not fair at all, and predatory to new players)
• Cease with drop rates below 0.01% (0.01 is literally one time out of 10000, how many more times will a player have to hunt for such items? Is it even worth it?).
• Potentially make it worth it to break tiles such as grass or furniture, maybe these could have a chance to drop something more expensive than 1 to 50 crowns?

Miscelaneous

• Display things like keys, locks, enemy markers, and other minimap-only icons on the full screen map.
• More occurrences of "set piece"/rare arcade rooms, like Tortodrone sites, or other Worldbuilding set pieces. Arcade has been stale for a decade, so if no new rooms are to be added just yet, making rare and special ones more common could help a bit!
• A way to check the average recent sell price of every item in game, to lessen the risks that someone asks for a price far greater than what most would give (scams, said plainly). Getting Crowns and energy in this game is not cheap, either in real money or time, so let's protect AH and Trading more.
• Map Markers for loot boxes, closed if they haven't been open yet, and un-checked if they are open but that player hasn't gone near them.
• Use some level-specific Mechanics more, Like all of the block palette Treasure Vaults use, or the IMF missile Launchers, or the wheel launchers, or the Collector level's punch canons, etc...
