It doesn't affect your dialog but it can affect dialog between the two.  For instance if you romanced ashely in ME1 and Tali in ME2 and take Ashely onto Tali's quest they have a tense moment.  Thats the only game I've played through all the way so there might be more if you romanced Liara and Person X if you bring Person X on Liara's mission.

This summer sometime they haven't given much detail on when.

If you have already played through ME1 and ME2 you DO NOT need to play multiplayer in order to get the "best" ending you just have to play through the game and manage to get. You may have to do a few sid missions in order to get the best ending but it is realatively easy. If you haven't played through ME1 and ME2 you can download a save file from www.masseffect2saves.com which doesn't even require you to own the other ME games. As for the multiplayer, while not as refined or clean as COD or Battlefield it is rather well done and is well worth the time to play, its alot of fun and the six classes add a certain depth to the game.

I understood the ending perfectly except for the part about the Normandy and my team being on it. It was simple you had three very distinct choices.

1. RED DEATH- you destroy every synthetic being in the galaxy pretty straight forward all geth, reapers, and TIM type people in the  galaxy are destroyed along with the Mass Relays.

2. BLUE CONTROL- Shepard becomes the AI god child that controls the Reapers what he does with this control is unkown.

3. GREEN SYNTHESIS- Shepard sacrifices himself to combine DNA with Synthetic Properties.  Basically everything in the galaxy stops becoming organic or sythetic and becomes a mixture of the two.

What was so hard to follow we knew all along the crucible would create enough energy to destroy the reapers the only question was how would this energy be release.  As for the Mass Relays being destroyed, the ships in the Mass Effect univers do have FTL travel it just means instead of taking hours to cross the galaxy it would take a few weeks.  Big deal its like going from air travel to boat travel slower but still manageable.

Try this website if you dont want to play through again and be sure to pick a complete Paragon character that way you will have the best chance for getting the synthesis ending.

I found the whole indoctrination theory to be full of more holes than the original Mass Effect 3 ending. I also found a website that talks about the theory.

I have Fallout 3 GOTY edition and I was wondering if anyone could help me. I have all of the expansions installed and it tends to randomly crash when i am moving from area to area outdoors without warning. I've tried every trick i know (like reinstalling, patching, checking codecs, compatibility mode, even using a game booster that shuts down all but essintial systems on my computer and the game) and nothing seems to work. I have a brand new Fujistu laptop with a NVIDIA GeForce 310M graphics card, 4 Intel Core i5 CPU, and i believe 4 gigs of ram. Does anyone have any suggestions on how to fix this problem?
