I finished this today and it was fun game. In some ways I'm happy with it, in other ways I'm disappointed. In the end it was a fun action-y 12-15 hour game full of good room designs for good fights. To me it didn't satisfy that fall/winter HUGE AAA title spot that Gears1 did when it came out. But then Gears was new and fresh and looked amazing. This is Gears...again, and it still looks amazing although not to the level above the competition that Gears1 was.
I'll get this out of the way:
Act 1 = looked weak, played weak
Act 2 = looked amazing, played amazing
Act 3 = looked great, played weak
Act 4 = looked boringly great, played great with no variety
Act 5 = looked amazing, played amazing outside final boss
+Having HUGE MONSTERS to mix up with grunts was excellent. Gave the standard fighting more variety. My favorite part was fighting a reaver in the graveyard in act.2 jumping from grave to grave to avoid its stabs.
+Shooting was still satsfying
+framerate was solid
+graphics were good. The engine really shined with destroyed cities/caves/rain/darkness. Not so hot at normal looking places in the daylight. Never noticed the lack of AA in the first one because it was so ahead of everything else. Now that standards have raised considerably this gen, IQ is a bit rough. Motion blur was good again, though caused problems during the reaver ride at high speeds.
+Witty dialogue OUTSIDE OF CUTSCENES when walking and playing is very well written. Makes for great memorable characters.
+Length was very good. Game was meaty.
+Mortar was good
+Introducing some actual plot like the mysteries in act 3 added to the game and made it more than just doom in TPS
-Cutscenes were terrible, especially the dom story
-Story pacing was weird. Normally you have a beginning, a middle, an end. With antagonist and protagonist development. Here I never had any idea where I was in the overall plot of the things. Like when I got the clear game achievement I was like "wait, what? That was the final boss? The game just ends here?" Seemed odd.
-Sadly game was seriously just Gears 1...again. I'm surprised they didn't at least add a TON of new weapons or new gameplay system or something to differentiate it. For most of the game you're moving behind covers using your chainsaw gun & sniper gun and shooting grunts who are hiding behind cover as well. As I said above, throwing in the giant enemies helped mix it up. But it really felt like it was more of the same (luckily Gears1 was excellent, so more of the same is still fun)
-Even though I'm glad the game was long. I don't think they had enough variety to fill that length. Some chapters really felt like they mixed it up (act 2) by having a new environment every hour. But some chapters like act 4 were just filled with tons of fights that were all the same in a ton of areas that all looked the same >_< The gameplay was strong, sure. But it just wasn't very exciting because it lacked variety.
-The vehicle stuff ranged from terrible (tank), bad (reaver), ok but shallow (brumak). Did not really add to the game. Brumak scene was extremely similar to the Metal Gear Rex riding in MGS4.
-I HATED the 4 person system. I don't really see why they did it if they weren't going to put in 4p coop. Maybe they were trying for 4p coop but in the end couldn't do it in time or something. But my problem with having 3 AI buddies is that THEY ARE TOO USEFUL. Like I'll walk into a room and they're already in the middle of it having killed a few guys and drawing the attention of everyone else. So I just pull out my gun and shoot all the enemies while they are firing at my buddies. I DON'T LIKE THAT. Too many parts of the game felt like what I don't like in war with buddy AI games: I felt like I was hardly doing anything. I was shooting a grunt here and there and there and then I'd hear the sound that everyone was dead and it's time to move to the next area. I don't feel like I'm moving the game but rather that the game is scripted and moving on it's own and I'm just staying alive between scenes. I strongly preferred the 2 person sections since Dom is useless and does nothing like Gears1.
So yeah, I actually really had a good time because the mechanics from Gears1 are so strong that 2 years later it's still fun shooting a thousand grunts and listening to the Gears say silly stuff. At the same time I do feel like it was too safe of a sequel and more of the same to the point that it didn't give me that amazing game experience that the first did. It was Gears...again and still fun. I just hope Gears 3 greatly changes up something to give a new experience.
I haven't played Multi, so that's just my take on SP.
