Ugh, Weekes and L'etoile are two writers I certainly do not want to write for Mass Effect, or any other game I'm interested in. In a game that's been always advertised as "your story" and about "your choices" those two with their massive egos decide to teach you lessons and impose their views on you rather than let you play by your own standards. I'd most likely refrain from bying the game if they would have major influence on the writing again. Especially Weekes.
Seriously, people lamenting the inconsistent writing yet want a writer back who's responsible for changing the nature of the genophage, turning a deranged criminal into an elite school teacher, changing the synthetics significantly and nullifying everything that could speak in favour of the Quarians in the Rannoch arc? How does that add up? If this dude believed one choice is good and the other bad not only does he let you know this, he literally rubs it in your face. Like in Mordin's loyalty mission where you pick seemingly neutral dialogue options and ends up taking a position on the Genophage and chastising Mordin over it. Then in the end you get your alibi choice in which renegade Shepard of course contradicts him/ herself. Same thing on Tali's mission if you talk to Xen.
His writing is fairy tale writing for children. Everything is black and white, here are the good guys, there are the bad guys. The good guys always end up repenting for their sins and joining the good paragon side, the bad guys who still support the other choice have the character of comic book villains, including (renegade) Shepard. Is this seriously the kind of writing people want?
I on the contrary think that it would do Mass Effect good to have a fresh start with a completely new writing team. With writers who A) are in agreement about their visions of what to write and how to write it. Alternatively with a lead writer who dictates the direction. So far I had the feeling everyone wrote what (s)he wanted. What Weekes wrote for Rannoch and with Edi and Joker pretty much contradicted what Walters wrote for the ending and what L'Etoile wrote before him at the same time.
B ) The new writers need to understand that giving the player choices is more than simply give them options on the dialogue wheel. The writing must support those choices, and let every one seem as the right one from a different perspective.
And C) they should not sacrifice everything for character writing like ME2 did. Characters are important, yes but so is the story and the exploring part.
If I had one wish free, I would give the writing to the Fallout New Vegas writing team, Chris Avellone & co. They have created a great story in the Fallout universe and I'm sure they can do the same in the MEU. Their story writing was consistent, their choices unbiased and meaningful and their character writing can very well compete with Bioware's. (In fact I liked Cass, Arcade and Veronica much more than all Mass Effect characters except maybe Javik). The Mass Effect writers gave us an exciting universe, which is the thing that attracted me to the games. Their story writing however was mostly disappointing to be honest and you can give Walters hell all you want, he is not the only one who screwed up.
