No ME3 MP included. Which sucks as it was the only redeeming thing in ME3.
It will be interesting to see if Bioware will redo the crappy ending or not. They really could get back into people's good graces by doing so.
I kind of wish ME3 MP would be its own thing, TBH, not tied to the "Readiness" factor. I did like the MP and found it quite fun, BTW.
I never cared for this "Readiness" Factor thing w/ the MP required to get a better ending for the SP, basically based on how most of this game was really a SP (Single-Player) game. We also know how EA and other companies can be, shutting down MP portions of games and all.
And it's not like ME3's had an offline skirmish mode version of the MP, so you could play against bots either...b/c I'd always worry about BioWare pulling the plug on the MP, at some point in time.
So, it now looks like the "Readiness Factor" for ME: Legendary Edition Collection here is going to be judged across What's Done Across All Three Games in this collection -

Also, The Extended Cut (from ME3) is the canonical ending for ME: LE.
Also, Pinnacle Station (from ME1) is just not in this ME:LE Collection.
EDIT:
Honestly, if they survived Ass Effect: Andromeda, I don't think redoing one of there most popular trilogies with all its DLCs(*) is going to be the final nail in the Bioware coffin.
I think this Trilogy is a license to pretty much print money here. ME: LE is likely going to be a big deal for console gamers, who probably never had the entire collection of ME1-3 all in one place; and now they're able to easily bring their saved games & Shepard characters over from one game-to-the-next with ease here in one big collection.
Sure, on PC - easy enough: have all your ME1,2,3 saves. I still got them. You can pull your saves and Shepards from ME1 to ME2 to ME3.
I think what I'm most curious about in this collection here: how much closer combat-wise they bring ME1 over towards ME2/ME3. Let's face it - ME1's combat ain't on ME2 or ME3's level. ME2 and ME3 was such a big jump in combat, compared to the original ME1.
Also, for this ME:LE Collection - I'd love for the new roll move from ME3 to wind-up in both ME1 and ME2.
