ME2...
Pros:
- great combat mechanics- well, better than ME1 although I still have a soft spot for them.
- Looked phenominal
- Character work was fantastic
- some great lines
- smooth transition from ME1
- the N7 missions were more in depth
- Kasumi, Zaeed, Overlord and Lair of the Shadow Broker were great.
- Conrad! The refund guy!
- Normandy upgrades gave you more of a connection to the ship
- Joker and EDI were priceless
- Blood Dragon armour and Collector Armour looked great
- Heavy weapons- Arc Reactor and CAIN FTW
- Kelly, because every ship needs a community bicycle
- Mordin! Nuff said.
- Larger scope. Larger main missions.
- No having 10 000 of the same weapons with different skins that you just ended up turning into omni-gel anyway.
Pro/Con:
- No elevators. I know they drove people nuts but I found that it kept me immersed in the world.
- Loss of semi-pointless planet and galaxy scanning. It was good XP and for those of us who have to complete everything, getting all the writings, turian insignias, etc was a must.
- Planet scanning in ME2. With the upgrades it was better, but I still mostly used it to lull myself into naptime.
- I miss the Mako, so sue me. I think had they adjusted the control mechanisms of the vehicle, it could have been viable. At least it was more durable than the Hammerhead.
- HUD's in ME1 and ME2 were both better than what I'm seeing in ME3.
- Global cooldown was a shock to the system and took some getting used to.
- No omni-gel. The mini-games were ok though.
Cons:
- Story... this really is a big one. In the end, I found that you just had to not look into it deeply, which was a first in my BioWare gaming experience and very difficult. I'm not getting into the story issues here.
- Lack of customization. No customization of companions. It's stupid, but when I first played, I thought I'd be able to buy all kinds of outfits to wear on the Normandy, mods for weapons, etc.
- Level Complete screen. Hated this. No continual XP gain.
- Lore reasoning for the thermal clips. (I'd have preferred they just pretended it was always like that rather than coming up with a single codex 'hand wave' excuse. I'd always rather have a weapon that I could fire again over the potential to run out of ammo and be SOL.)
- Poor field of view. Seemed a lot less than in ME1.
- Couldn't whip out a gun and shoot random things in a public place. Why stop me from my fun? It was 'society', right?
- Linear levels, with no ability to go back to them if you missed an upgrade or something.
- No helmet toggle broke my immersion on my very first playthrough when I met Tali wearing the Blood Dragon armour and Tali seemed to recognize me.
- Not enough money and not enough pointless stuff to spend it on. Not nearly enough armour or weapons.
I'm sure I could go on in all three categories but I won't. I found that in the end, the Pro's allowed me to get over the Con's, and enjoy the game, but I'm not going to sit here and say ME2 was the best thing since sliced bread.
I think a lot of people who flat out state that ME2 was 'universally loved' ignore the fact that many of those people shared my list of Con's but, like me, felt that the Pro's made the game a good experience overall. Most of the "It was a great game" reviews came with a 'but...' attached.
I can't make any judgements on ME2's place in the series until I play ME3 to death. I'm constantly changing my opinion of the demo. I'm choosing to believe the kid is part of Shepard's PTSD because that actually makes for some intriguing story situations rather than a fairly basic attempt to get me to really 'feel' how EVIL the Reapers are when I ALREADY KNOW THAT.
