Well, I'd give BW all my material immediately, no questions asked (most of it is made with there assets anyway
).
There are of course a number of problems that preclude another official ending DLC from ever happening, most of which have already been mentioned here:
1. Not commenting on any mods is a win-win situation for BW. The people who like the original endings don't have to care and some of those who did not have an alternative, so there is no need for them to act. On the other hand, taking any action from their perspective is a loose-loose. If they condemn the modding efforts, they anger fans for no reason and if they were to make a new DLC, they would just resurrect an issue that has largely been put to rest these days - not something any marketing department in their right mind will recommend.
2. While I personally am happy with the mod for now, it would be way, waaayyyy below BW's quality standards. They would have to remake the entire thing from scratch with their production values. Not necessarily a cheap thing to do.
3. When making these mods, we basically hack the game and force our code in (I think giftfish from the ThaneMOD team once put it very well: we beat the game with a stick until it does what we want it to do). This can introduce a whole lot of bugs (and we had them) and is generally not advisable, so again, they'd have to start from scratch using their tools. Not to mention that - as I wrote in my last post - the mod as it is will probably not run on consoles anyway.
There are probably a gazillion more reasons not to do anything remotely like this, not the least of which may very well be that they just don't want to.
I would of course be ecstatic if we could figure out how to make all those PC mods available on consoles but I don't see that happening and as other have said, I too am just happy that BW didn't shut us down from the get-go (something we were very much anticipating back in the days).
I do however have the hope that maybe, just maybe, BioWare will add some sort of modding support to ME Next. That would really make me happy. I think the chances for this actually happening are extremely low but - given how much the DA:I modding community has already achieved with that FB3 game - one can hope that they will eventually see the light.
I will continue to mention it whenever I can. Maybe the more people do, the better our chances get.
