We can accept now that Andromda was a failure. But do you consider it canon?

I think it might have something to do with

Sure. But who cares tho?

Its canon in the same way that the Star Wars prequels, Indiana Jones and the Crystal Skull, and Halo 5 are canon

which is to say canon, but I hate it

But just because of that, doesn't make the game a failure.

Here's the scale of how well a game does:

Huge Failure ---- Failure --- Barely a success --- Success -- Huge Success

I think most can agree that the game isn't a huge failure or a huge success. We wouldn't be having this discussion if it was a huge success, and the last quarter results show it wasn't a huge failure.

We don't know enough to know if the DLC and further updates were cancelled due to the game failing.

I think if there's money to be made... it would be made.  Not sure how it could qualify as any sort of success when the studio that made it has been shut down, and the for the first time in the series' history, there's no DLC.

Yes. I consider it canon. Why not?

No.

It's not hugely problematic, but I find it doesn't fit the OT at all.

Not its technology which is more advanced than anything we see in the OT, especially the magic driver which should totally change how we travel in the Milk Way and the Nexus which a ship that breaks the rule that ships too big or too heavy are inviable. But also, the fact that everyone would have know of the Arks (but never mentioned them) can positively change the thought process of everyone during the Reaper war. All that discussion that if we lose we are extinct are suddenly not true anymore.

When one plays the OT, one has to ignore Andromeda. So why bother considering it canon them? Of course you can, but I have a feeling many won't or simply won't care. Andromeda is something that doesn't feel part of Mass Effect. 

Canon ? Not for me.

It is canon, whatever you like it or not.

Deal with it.
