No, the entire game as a whole doesn't suck...but it sure as hell isn't the "OMG 10/10 SHUT UP AND TAKE MY MONEY" game that the last 2 were. I would go so far as to give it a 5 or 6/10, mainly for these reasons: (yes, in that order!)
1. The ending. I'm sorry, but after 2 games of KICK ASS storytelling you can't just end the series on a literary cluster**** of an ending. We were promised multiple endings based on our choices; we did not get that! This (
http://jmstevenson.w...-mass-effect-3/) is a good read if anyone is looking for a real literary analysis on why the ending is crap, and it is a neutral standpoint as well.
2. HUGE lack of "real" (30mins-1hr+ long) side missions. In the previous 2 games, there were like 10-15+ "real" side missions. Yeah, ME1's side missions were basically the same prefab units in different layouts on each explorable planet, but at least they were REAL side missions with a wide variety of enemies. In ME3, we get a bunch of bull**** fetch quests and THREE "real" side missions: grissom academy, the ardat-yakshi temple and the fuel reactor mission; all the other N7 missions were WAAAY too short to be "real" side missions as they can easily be done in 10-15 mins. VERY dissapointing, not to mention a cheap tactic by the rEApers to make us pony up for DLC. (which I will not be doing; you don't manhandle consumers into spending money like this!)
3. The useless journal! I mean, what the ****? The previous 2 games had a journal that explained every step of a mission and where to find key people in case if you got lost; all we have in ME3 is a vague description of the ENTIRE mission. This was especially annoying with all the fetch quests when they don't give you a specific location of where the person is.
4. Not as much interaction with your crew. A LOT of the conversations were similar to the one-liners Zaeed and Kasumi had in ME2. I also found the dates with LI's to be a bit lacking; they really should have been more than some 3 minute cutscene. Not exactly asking for a 30 minute one either, but after finding out shepard's mom was still alive, I felt that really was a missed opportunity for shepard's & his/her LI's family to meet each other!
5. Not really sure if this belongs under #4, but some loyalty missions for crewmates like Kaidan/Ashley that weren't playable in ME2 would have been nice. Or maybe "doing a huge favor for a friend" missions since they probably make more sense in ME3 due to everyone already knowing shepard well...haha. But you get the point.
