First of all, let me just state the obvious: this thread title is an oxymoron.
As to the point brought up by the topic starter . . . sounds to me like they have never played anything except RPGs their entire video game lives, and therefore find aspects that most varied gamers loved to be 'boring'. Why is it boring? Because it doesn't involve constant level up, management of inventory or bland combat? Let's take on your opinions one by one and see where you and I differ:
Point 1: You say the combat in this game is boring. In comparison to what, may I ask? Because if you're comparing the combat to the first game, you can't honestly be saying that ME 1 had a better combat system, could you? Sluggish camera controls, no point-specific damage, poor aiming, and an irritating-as-hell 'cool-down' system for the incredibly bland, limited selection of guns? ME 2 clearly has the better design in the aspect. It may not be to your liking, but this series always aspired to be a shooter/RPG. Now with this game, they finally succeeded at having the right balance.
Point 2: 'Making nice' has nothing to do with this. You either treat your crew the way you think they should be treated, or you go against your instincts and kiss their ass all the time. There is no 'right' or 'wrong' way to answer, honestly. It's just being true to yourself and what you actually feel. A crew member's loyalty to you isn't based on how nice you are; it's about gaining their trust, despite personal differences. That's why the loyalty missions exist in the first place. Otherwise, why would you need them if you could just make them disloyal by being an ass?
Also, I think you're way off base when you say the dialogue options are constrained; on the contrary, I felt even more freed up to make a much larger impact on my game because of the clearly more diverse dialogue options available to me. Again, if you do not see that, I really don't know what to say. Except that you're wrong.
Point 3: Okay, this point seems to be mainly a story-based complaint. You don't like the way things played out for Shepard, then don't play the game. There are plenty of opportunities to tell Illusive Man exactly what you think of him, and you can even defy him completely by the game's end. You're not his 'lapdog' by any stretch of the imagination; you simply work with him out of a need to fight for the greater good. And as for Jacob and Miranda being Cerberus ''cheerleaders'', I've never heard anything more absurd in my life. Jacob openly admits right off the bat that he and Cerberus don't see eye-to-eye on many issues, and a loyal Miranda even backs you up if you decided to destroy the ship at the end of the game. How are either of those actions 'cheerleading' for Cerberus?
Point 4: Okay, this point I actually agree with. Scanning the planets had to be the worst 'change' made to the exploration feature from a pure fun standpoint, however i have to say they succeeded at what they aimed to do, which is get me to actually CARE about exploring. I made sure I had all the needed upgrades to my ship by the time I went through the Omega 4 relay, and that wouldn't have happened had they not put so emphasis on this aspect. So I'm torn on this. While I completely agree with you that it's boring, it is certainly NOT 'pointless', and it does pay off by the end. So you do it for a reason, and the game ultimately rewards you. It raises the stakes a bit and gets you more active in things other than just fighting all the time.
Point 5: is the only point I find myself agreeing with you 100% on. I can't tell you how disappointed I was when I realized I couldn't customize my other armor in the same fashion I could my standrad N7 Armor. It would have been nice if you could choose to take the helmet off of the BDA, CA, TA, etc. I often felt discouraged from using them whenever I did a mission simply because I wanted to see my character 'act', but with the better armor I had no choice but to cover the face up. So yes, you and I are on exactly the same page as far as that is concerned.
Point 6: Again, this opinion has me questioning your mental health? Lacking customization? No looting? Where are you from, man? Lack of inventory means anything you pick up on the field instantly get applied to your character. Enemies drop ammo all the time, you still find health packs for you allies, research files (which help you with this upgrade system you claim doesn't exist), etc. And even guns are dropped on the field that you can scan and reproduce for yourself. None of that worked on the first game, so again, this is a step up, not a step down.
As for the customization and upgrades, not only do you have an entire slew of options for you and your allies in terms of weaponry, armor, biotic and tech, but you can also make upgrades to your ship that will help you in the game's finale. there was so much available to me, that I barely scratched the surface of what I could upgrade on my first playthrough. Did you just not investigate ANYTHING while you explored the massive world of ME 2? Because to me that seems like all kinds of customization is available.
So, for the most part, I think you're off your rocker, with a couple of exceptions. I'm very sorry you thought this 'great game' was also 'no fun to play'. That contradictory viewpoint is hopefully nor shared by many others, which means most people who played this game will love it and look forward to the final installment. I have issues with this game, too, but they are minor. I certainly don't think any aspect of the gameplay itself is lacking in any way. It is much better than its predecessor, and I hope BioWare continues to go in this direction for ME 3.
