I have a few questions about the game:

-Is it moddable? if so, how much?

-are there dragons in it? if not, can you consider adding them? also in expansions?

-is it planned to support and upgrade the engine once you release it, for some time?

-would it be possible adding full flight capabilites for player and enemies in it? and transforming into other creatures (dragons, chtonianas etc)?

-will my GTX 580M be able to run it properly? I have a good CPU.

-are there capes and cloaks with physics? so that they move accordingly to actions and avoid clipping?

-are there passive skills? if so, can they be modded/added?

-can we create new classes? or at least new specializations, if you will implement them?

-can we increase the damage types? or can you considering adding a "light/holy" type of damage?

-does the engine use multithreading? are you considering a 64-bit exe?

-does the engine support continuos-cast spells? such as diablo III's disintegration ray, or Skyrim's concentration spells?

-how many npcs can the player hire to travel with him/her?

-how much can we customize our in-game avatar? I don't expect stuff detailed ala Oblivion-Skyrim-Neverwinter nights 2, but something like diablo 3 is somewhat unacceptable.. Diablo 3 was a huge disappointment.

-will we be able to alter the loot system so that it is more "fair"?

-are there "item sets"? sets of equipment that, when worn together, give a special bonus?

EDIT: what kind of locations we can see in the game? I have read about exotic places such as deserts, will we see also sacred/magical places such as ruined temples, underground cities, cathedrals, extra-dimensional cities?

EDIT2: how much control over music do we have? is it bad like in the Elder Scrolls games (oblivion-morrowind) or more refined, like Japanese rpg-baldur's gate?

EDIT3: will we be able to customize enemy AI and make scripted boss battles, like the ever-famous Dracula from castlevania?

EDIT4: is the engine finished, or is it going to get furtherly optimized?

EDIT5: can someone list all the weapon types and the damage types known until now?

EDIT6: can a "template" system, similar to D&D, be implemented in the game in order to reinforce characters and [quoting Raziel] "allow them to become less human and more... divine"?

EDIT7: can we change the font used ingame?

EDIT8: how does the engine handle sounds? from sfx to music (does it support pitch variations etc). Can we add, if present, customized battle music and custom boss music? (similar to JRPG but unlike Diablo, which was disastrously lacking concerning music)?

whew. sorry for the wall of text.

I hope you are not trolling us ...
Most of the stuff you ask here is regarded to the game engine .... Idd suggest you ask this kind of stuff on the official game forums.
As far as I can tell dragonfall is just a DLC so I don't think they made major changes to gameplay . You can't import your character and I haven't visited any exotic spots (besides the manor) and its all pretty much standard till now.

since when asking questions relevant to the game or the game engine is trolling?
if you're so bothered tho, I can delete it.

Usually people are expected to do SOME reseach themselves before asking million and one questions. Much of the information is readily available on the net like , [url=http://shadowrun-returns.wikispaces.com/]Shadowrun Returns Wiki or Youtube. You seem to be even aware what kind of game it is. I'll try to answer some questions but I have not yet played it but have watched review videos and parital play thrus of base game on youtube so my answers may not be absolutely correct.

Let's clear one thing first: It's not ACTION RPG like Diablo at all (pretty much perspective and all it brings is the only similiarity). It's story based isometric single player RPG with real time exploration and TURN BASED combat. Shadowrun setting is mishmash of fantasy, magic and sci-fi based on alternate future earth.

I think it's "2.5D" game with 2D backgrounds and objects but with 3D characters. I did not see screen rotation in any video so the view angle is static. (official description: Engaging 2D/3D Art Style. Shadowrun Returns mixes dynamic 3D characters and lighting with a vibrant, hand-painted environment. Illustrated character portraits bring conversations to life.)

It's moddable, at least to an extend and comes with it's own editor.

It's still being patched but the future content depend on success of the game and dragonfall DLC. Some possible DLC locations were mentioned already durring kickstarter. If more DLC are released, the engine will be updated to accommondate any new features DLC brings (easier to maintain) but that does not mean that original campaign will make use of all features.

There is no "flight". I think some things "float" but it's artistic presentation, not actual flight.

Character customization, development and especially equipment is limited. Iirc most if not all enemies don't even drop loot and bodies do not persist.

Most things about modding and engine capabilities are probably better asked on official boards or steam forums (lot more modders there). I do have distinct feeling you're looking something completely different. Do bear in mind game had less than tenth of Diablo's budged.

I'm going to ask developers directly, in fact :D thanks!
it's similar to NWN, this game here, in terms of mechanics?
