SystemShock7: Well, given the quality of W2's story and how it plays out, and all the details implemented throughout, I think there's little the franchise could learn from other games in that aspect.. but, a few things that I would like to see implemented in Witcher 3:
From other games:
* A true open world (ie, open map) Being able to go back and forth between all cities/places in-game. Maybe even add a few more locations; they don't have to be huge, maybe a few more Lobindens...
* More NPC meshes/textures. There are too many "repeats" among the characters. Many a time in W1 and W2 you see a crowd of people with a few sets of twins and triplets.. It would be great if more body meshes/textures were added, and especially more face meshes for the NPCs.
* More player armor meshes. As with NPCs, even though there are about 20-some player armors in game, they all are based off the same mesh, with about 3-4 different variables.
* More weapon meshes. Same as above... too many weapons based on the same mesh.
From W1:
* Delayed effect on choices made. *SPOILER* Remember in W1, the first decision the player had to make during the prologue, whether to defend the lab or fight the beast? At the time it seemed like nothing, but then, half way though the first chapter, if you didn't defend the lab all the formulas are stolen then you have to fight early on with the mutated dog?
* Neutrality path. In W1, the player could take 3 paths until the very end. In W2, only 2.
* PC UI. Enough has been said about it.
the best swords at chapter 1 looked weird really weak swords looked kinda cool I hated the robust sword and superb cutlass hilts they look like shit I mean blue and red!? orange and green!? wtf were they thinking. also the best steel sword looked exactly like superb cutlass.
I agree with the choices in TW2 it was too apparent when you were making a choice even and it was always in dialog form cept for the Loredo one.
also getting new armor and swords was too easy. I spent an entire chapter saving orens to get a better leather jacket in W1 and it really felt good since I worked a long time for it now armors are on random treasure chests you don't feel any attachment to them whatsoever since you 'just picked them up'
