I just got DC too, something with PSN?

@Oblivionz

Sorry bro..dc from PSN. Damn what a waste, half-through silver already.

So the way it works is that there are two systems, one is Readiness which is a percentage and the other is your Galaxy at War score.  Both combined give you a number that calculates along with your choices what ending you get.  You need a score of 3750 to get the Master and Commander achievement and a minimum score of 4000 to get the best ending.  Now your Readiness percentage starts at 50% which is not affected by playing the single-player.  50% seems to be the absolute base in that it can't go below that and multiplayer makes end game much easier.  Readiness can only be affected by playing the multiplayer.  So to get the perfect ending, you have to get a GAW score in single-player of 8000 and have certain correct choices.  In order to negate these choices you have to get a end game GAW score of 10,000 (or 5,000 once you calculate in Readiness).  The bad news is that there is a decay system attached to Readiness which is linked to real-life time.  However note that Readiness cannot go below 50% and is so the decay will only affect the bonus from multiplayer.  Something like 1% a day.

What this means in regards to the endings is that to get the perfect ending, you have to play through the singleplayer game and do EVERY sidemission to get the perfect ending.  Now you can do multiplayer so you have to do less sidemissions but that bonus will decay in real-time.  You can take your time but you'll have to play the multiplayer or the iOS game to maintain or increase your readiness bonus percentage.

So the multiplayer makes getting the perfect game MUCH easier.  It is however doable in singleplayer only.  Also when you import your level 20 character you get a GAW score of 75.

And yes the decay system is a horrible idea and I hate the person who thought it up.

Source is a guy who has played a build of the complete game.  Check spoiler group for more details.

Again it is possible to get a perfect ending without the multiplayer but it is much harder.

Formula:

Overall score = GaW x GR.

GaW is affected by SP and doesn't decay over time.

GR is affected by MP and decays 1% every day if it is above 50%. If you don't play MP at all, it is always at 50%.

Got this from Bioware ME3 forum
Good thing still can get perfect ending from single player alone, just need to do every missions

Great. Just hope that the side missions are not too hidden away or missable.

sigh. i thought we can really complete that match, until u dc. U leave me and that stranger. of coz we lose since he did not even cooperate properly.

anyway, i did complete silver a lot of times with a bunch of strangers but that bunch of strangers knew what we need to do, what to do and how to do it correctly.

the only thing i want to achieve now is complete 1 gold match. anyone want to join me?

I just  tested me3 demo campaign mode. I never played previous ME before.. But im curious what you guys choose to play on campaign mode? Role playing or action? Is role playing harder? Because i only tried action.
The demo version had alot of screen tearings and frame rate problems. I hope its not like this in the final build..
