That's the first installment, when you compare the combat in Mass Effect 1 and 2 to TW1 and TW2 the Witcher games look unplayable in comparison. In fact, TW1 is literally unplayable to some people with how weak the combat system is and TW2 is borderline unplayable without the combat mod, the targeting system is a joke.
I actually found the combat controls in TW1 really natural after a while, I didn't have to think about switching between stances I just did it. I actually found TW2 combat more finickety - especially when combined with the (bad) decision to make it so you couldn't chug potions in combat, which took away your "get out of jail free" card when you screwed up.
I find everything about ME1 more clunky; ME2 was fine and ME3 was just far better defined. But shooty combat is a completely different beast to stabby combat; it's harder to screw up. But I'll take the combat from The Witcher series over the two Dragon Age games I've played.
I completely disagree, the Council actually offer reason with their points, especially in Mass Effect 1 in that some of them are torn on your position as Spectre as well as them only listening to the fact. Emyhr is far more cartoonish in comparison, even compared to literal machines in the Reapers the Reapers look more morally gray with their intentions. Udina himself has you questioning where is alliances lies, he always seem to be wanting to better the Human race offering a nice contrast to say a Paragon Shepard in that despite knowing that Udina wouldn't be the best representitive for the HUman race he sure would most likely be the best thing that happened to them.
Emyhr had something like 12 lines the whole time for **** sake. He almost wasn't a character at all.
We'll just have to agree to disagree there then

The council, to me, are just weak political satire - shown as being ineffective and indecisive; a bland statement that democracy doesn't work... best to just let them die in ME1 - not that the replacement is any different to further hammer home the previous statement.
And no, Udina's alliance is to Udina - bog-standard, power-hungry political leech; I've never questioned his motivation until he was indoctrinated then it was just a matter of "meh, cop-out".
Emyhr's character however is demonstrated by the people whose lives he affects - from Geralt, Yen and Ciri to the Lodge and the armies on the battlefield, the Quartermaster, the widow... His motivations and actions are akin to those of any number of kings or rulers from history; he's not evil or cartoon villainous - he's a better portrayal of a Feudal Monarch than Udina is of a politician.
Just compare the the Wild Hunt to the reapers
Wild Hunt - We wanna **** Ciri and get the powers because standard generic villainy of seeking power
Reapers - Wanting to strike a balance between synthetic and organic life
Totally missing the whole point of the Wild Hunt - they're the Vanguard of a race that's trying to survive. Only the blood of the Hen Ichaer has the power to allow them to transport entire populations across worlds - that's why they're after Ciri.
The Reapers are the result of a stupid programming error on the part of Leviathan.
Ciri is absolutely a Deus Ex Machina as much as she is a Mary Sue. The White Frost pop out of nowhere in the game and surprise surprise, Ciri is the "chosen one" who can stop it, this is some Lord of the Rings level of cliche bullcrap. By definition that is a Deus Ex Machina, they don't even explain how she stops it, it's completely absurd and forced.
Ummmm - no, the White Frost is central to the entire story from the beginning, you even visit a potential future world where the White Frost has brought about the end of civilisation in the original Witcher finale.
How Ciri defeats it is irrelevant - she was always the only one that could. The decisions you make throughout the third game determine whether she has the independence and strength to survive.
The duration of which the characters are thrown into the mix doesn't somehow nullify them from their status...
Actually it kinda does - a Deus Ex Machina is when you pull your finger out of your arse at the last moment to go "TA DA - this solves the unsolvable". The Elder blood being the only way to defeat the White Frost is central to the Witcher lore from the beginning.
The starkid is a last minute arsepull, the child of the elder blood isn't... the fact that it's Ciri ... maybe.
Had BioWare finished ME3 with some kind of big Harbinger moment which could lead to the downfall of the Reapers that would be far less of a Deus Ex Machina as he foreshadows events through the first two games - and is pointlessly discarded in the third.
World building has never been a strong point of the Witcher books and I absolutely find the Mass Effect world more impressive...
Impressive in the amount of original work, agreed. I did however have a sense of Deja Vu first time I played Mass Effect - I was sure I'd played it before - it heavily drew from so many SciFi tropes.
I find that because the world of The Witcher draws more heavily on European architecture and folklore it's better realised and fleshed out. Is that more impressive? Maybe not. Is it a stronger, more lived in feeling world? I think so.
The closure is forced and the ending gave us now explanation as to how we got there. You see Ciri go into the portal thing and based on some arbitrary choices she either dies "because reasons" or she defeats the white frost "because reasons", it was perhaps the most rushed thing i've seen in the Witcher trilogy.
Again, I feel you're missing the point. How she defeats the White Frost is irrelevant - whether she has the strength to survive doing so, whether you nurtured her independence or "daddied" her too much; that moulds her character, gives her the will and ability to survive.
I mean really, how do we defeat the Reapers? They come along and say, "Ok, your turn - pick a button". I hated that in Deus Ex : HR and I hate it in ME3.
