I don't understand the hype about TW3, I played it and I really can't say I will play it again.
From the whole witcher franchise I liked the 2nd game best as I really got invested in the world and its characters, with TW3 there were a lot of new characters introduced which apparently I should know ( but didn't ) and instead of dealing with what happened with teh people I met during TW2 I get a lot of pointless fetch quests.
Also TW2 had challenging gameplay , TW3 was pointless buttonbashing and looting was unrewarding
So no please not like the witcher 3.
I also feel that every dev is focusing on world size, amount of playable hours and **** like that and I truly hope that Bioware turns their **** around and focus on quality again.
I'd rather play an 8 hour game and immediately start over again, over a game which lasts 140 hours and basically plays like an MMO.
For me ME4 or MEA should be about proper pacing, a non generic story, optional dating, real meaningful choices which alter the game if only on a personal level and exploration where you actually feel a bit of wonder when entering a new valley when you turn around the corner.
Oh and worlds that feel alive none of that static stuff we had in ME3.
If I had my way in this it would be:
A story like that of Bioshock Infinite or kotor 1
Level design like that of assasins creed 2
Immersion into a world aswell as excitement I felt when playing Thief 3 deadly shadows
Character progression like in Fable the lost chapters ( aswell as storytelling I might add)
Also I would address the ending of ME3 even if it basically says that in teh end Shepard got indoctrinated and we lost the milkyway to the reapers in teh end, it is infinitely better than teh RGB(A) endings we got
