Let me start out by saying ME2 was probably the best game I have played, story was great, characters believable and the visuals were top of the line. By all accounts and purposes, and I know Im going to get flamed for this, it was a step up from Mass Effect 1. Better shooting dynamics, more epic story. I know they say Saren was an easier enemy to be scared about but when you think of it in the first one you are fighting one Spectre, and one Reaper, in the second game you are fighting (SPOILER) a whole civilization of people under the command of Harbinger. A bit more of an immenint threat. (END SPOILER)
Also the pacing was probably the best in a game Ive seen that wasn't an FPS. Usually in games longer then 20 hours I get bored. Maybe its because I come from a FPS background of gameplays that are 6-10 hours long but the numerous sidequests, in ME1, DAO, FFXIII, Borderlands and well really any RPG they seem to get repetative. In ME2 they took out the cut and paste sidequests-Go here kill this-and replaced it with ones that every time had a different backstory and everything. I would love to see more content in ME3, but it shouldnt screw up the pacing. Ex, in DA:O it seems that the blight stops just so you can walk around the map and help out everyone in the game. In ME1 it seems Saren stops looking for the Conduit as you fly around picking up artifacts and such. Bioware go big for the time, I would love to see a 100 hr long game, hell I would pay 100 bucks for it no problem but keep the pacing. I had no problem going around helping out my squad as the galaxy was under attack because they were my troops and I cared about them.
But it had its drawbacks and most have been said however I dont think a few have. I will name them all anyways
-Renegade/Paragon actions: Have some of the paragon actions blow up in your face. Like in GTA4 you let some guy walk, good for you, now your a good guy, and later in the game he finds you and lo and behold hes pissed at you for making him beg for his life, now hes not on your side and wants to kill you. I would love to see some actions, (SPOILERS) like letting the Rachni go or helping out the Quarian on Omega (SPOILER END) and have that blow up in your face. Sure you did a good thing but maybe the NPC wasn't entirely truthful about their intentions and boom you screwed up and have to fix your mistake.
-LI's: (The whole point is full of spoilers to illustrate it) After my numerous playthroughs I finally found out that Jack really was the best LI in the game. She had depth, not a pretty cheerleader like Miranda or the sweet and innocent Tali(loved them both dont get me wrong) but Jacks backstory was just amazing and well I cared about her. However after the cutscene before the suicide mission she said the same damn thing when I went to talk to her. She just let herself close to someone, she should have something to say. I invited her up the the room but again all you can do is sit or lie with her. Some after diolouge would be nice, hell it would only have to be a few lines in another conversation after and it would be good.
-After game dialouge: This might not be a big deal because we dont know how the hell the story is going to end, Shephard might die the hero, in some cases he/she may already be dead, and nothing against all you guys with ideas on the plot of the game-some are great-but bioware is king at stories, they know what they are doing and probably have had an idea of what to do since ME1
-Upgrades-ME1 was way too much, ME2 was a touch too little. Compromise and why not have a tech tree like in Civ games for upgrades it would be kind of coo lbut maybe not in place with the RPG game. Also make it easier to see what you have already upgraded, I found it kind of annoying looking through every single one of my upgrades in chronological order to see what I had upgraded. Loved the ship upgrades though, that was a brilliant plan.
-Quick rant here excuse it please. For all you people saying make the LI's, sex scenes, and loyalty missions like DA:O, I wont say your not entilted to your opinion and this is only my opinion, but I dont think it would work for ME2, in DA:O you have to get their approval and their loyalty and such and they dont know you so yeah talking to them makes them trust you more, however in ME2, in the words of Mirada, Shepard is a bloody icon, everyone knows whats shes capable of and thats why they ask Shepard to help because he/she can do it, Shepard is the best at it.
Other then that make it just an amazing epic story, a few wisecracks from Joker and a fast paced, twisting, amazing melodramatic story, youve done it twice before Bioware, get a 100 Metacritic score, we kow you can.
