Pros: Weapons design are cool, graphics decent but animations seem worse than the previous two games.
Cons: Next to no decisions made in the past two games carry any real weight towards the conclusion in the third game. No final boss fight like in the previous two games. Crew members uninteresting, especially the new members. Ending disgraceful.
Mass Effect might have been the greatest game franchise so far. BUT:

Summary: Following is a rather lengthy review, which is free of spoilers. If you're not interested in the finer points, please jump ahead to the conclusion. The Collector's edition: To make it short: Not worth your money. Not if you're a fan, not if you're a collector. All of the included items are neither unique nor complete, and the CE is probably limited to all they could ever possibly sell plus a few.
Summary: This is a game that should have been a masterpiece. It had all the elements it needed, but somehow Bioware didn't know what to do with them. The combat is excellent, and the beginning is brilliant. And then comes EDI (also called HAL). The new companions are not good at all. The choices in the game are limited. And the ending is really, REALLY terrible. I wonder how someone can be so blind and not see it. It's quite obvious!
Summary: The ending is ruined by an ancient greek plot device to end stories. It is totally convoluted, lazy and classified as a writers co out. Effectively as imaginative as a Scooby Doo Ending. Some random unseen character jumps out of no where and claims he is a god and you have 3 colour choices to choose from. Not only is this unrelated to the rest of the game it is so bad that it ruins the rest of the experience of even the first two games. What an epic mistake.
Summary: Mass Effects main draw was the constant promise that the player's choices throuthout the 3 games mattered and that come Mass Effect 3 those choices would pay off in a big way. It was all a lie when you reach the end of the game all those choices you made from ME1-3 are thrown out in favor of and ending so badly writen that it makes no sense and actually destroys the games own logic that was set up throuthout the series.
