i think the crafting screen could have some indicator on how many items you can actually make of something... i.e. if you have 100 wooden logs and it costs 5 to make planks you just see what materials you need to make something with the tooltip in the list on the left, but it doesnt show anywhere that you can make 20 in total.
maybe a little number near the craft button or under the right info screen could be added to show how many you can make in total with the materials you have at the moment.
and i think the inventory feels a bit "very big" right now with 4x10 rows of the normal inventory and 4x10 extra rows for materials that already stack to 1000 (?) per slot.
and chests are compared to that just 4x4.
and it doesnt seem that i.e. each enemy has the loottable to drop 10 different items (i.e. feathers,eyes,scales,feet,wings,meat,fur or for robots metal,wires,screws,bolts,weapons etc like some other games have.) no idea if you later get a ton of drops so it will fill up pretty quickly with all sorts of loot... but i doubt you i.e. find a random weapon on every enemy or so...
so do we realy need such a big inventory that can hold items "to build 10 towns" where a chest can just hold a fraction of stuff... (well they are just wooden chests, i guess higher tech chests hold more items.. i.e. the ship wall chest does i think)
i.e. the terraria inventory was usually filled with all sorts of random items and especially materials that stack to 200 (?) so you actually had to store some stuff in chests and prepare before doing long mining and go down with a more empty inventory it you want to come out with more loot.
i saw that there are slots for "accessory on the back" (probably "deco" capes and wings?) i wonder if there are any backpacks... and if you have one equipped it could expand your inventory... i.e. by default 1-2 (?) rows of normal and material inventory space and a backpack adds 1-3 rows (or ir could add a number of slots instead of full rows) to it (maybe low tech ones add less slots).
well just an idea... i probably get yelled at anyways for thinking that the inventory is "too big", it just feels like you could carry "everything" and have no need to store anything as you probably never really run out of space, except when you find like 30 random weapons or so...
and the furnace doesnt require coal or wood to smelt stuff (it is so advanced it keeps burning forever) ? well i guess the torches or the campfire dont run out either (they could go from "a lot of light" (100% light) to "dim" (20% light) in a game day worth of time and could be "refilled" with wood like you repair a pickaxe with ore, as in clicking it with wood in the hand? think of the fireplace in "dont starve"), there is always higher tech stuff that wouldnt run out of "power" anyways. i.e. if it runs on electricity it could require some wires 10 tiles near it or so... and lamps (high tech torches) later wouldnt run out of power. (and yes i think torches light up "too much"... especially underground)
but it is not like you are swimming in wood anyways once you cut down a few trees to throw that into a smelter to smelt iron or to throw on a campfire to cook... maybe later "smelters/cooking places" require electricity and even higher tech ones could "smelt for free"?
i guess it would be too "annoying" if you had to "refill" torches or the campfire to cook something... *shrugs*
but it also could create new situations: i.e. a abandoned mine just barely lit up with torches that are burning very low and light up more again after you used your torch or wood on them. (well you dont need to use coal to create new torches, just wood to light them up again)
or a abandoned dark factory with no power.. and once you found the generator and filled it with coal (or build a new one and wired it up) it powers up the wires and all the lamps slowly flicker on again and the machines start to rumble and build robots to swarm and terraform over the whole planet (a la terraria corruption).......... AAAHHH it is not turning off again... too many robots... !!! SEND HELP !!!
(quest update: you hear from a human traveler that a planet is overrun by terraforming robots...)
(or: gratulations, you just doomed this planet... will you run away or undo what you started? (both choices might have consequences later))
