These are my responses to the major points, and opinions on the game and the franchises' direction.
1) As concerns the Mako. I understand that driving in the first place is fun, and certainly cruising around on a low gravity planet in a rocket car is fun. However, when every single planet is an emulation of the coldest part of the Rocky Mountains, the joy rapidly fades. Not to mention the fact that the parts of driving around that actually require driving, i.e. mineral collection, are essentially pointless. So all you really have is landing on a planet to drive to objectives, with large amounts of cliff sliding in between those two points.
Yes, driving around gave a tangible sense to the size of each world, but I feel that not having all the missions wrapped up in a single square kilometer, or on the 2 city blocks that previously made up the citadel gives a much better sense of the size of these things, even if it is more subtle.
2) THANK ALL OF HOLY HELL AND HEAVEN FOR THE ABSENCE OF THAT ORIGINAL INVENTORY SYSTEM. I was unaware that anyone liked that at all. You should also scarcely complain that the weapons selection is lazier, when in the first game all the weapons were essentially the same. All that changed were minor improvements in the 3 attributes, a choice between 1 of two models and about 4 colours. The new weapons at least have different advantages and disadvantages. Burst fire as opposed to single shot, bolt action v. auto sniper, etc. And the upgrading system is sensible rather than eye scratchingly tedious.
3) I had almost no glitches at all in the game, but then I played the PC version. I also did not notice grammatical or spelling errors at all. But then I am a bad judge of that since I generally just let my mind auto-correct that kind of mistake.
4) There were plenty of new characters in the game, and the old characters react rather like I would expect. In fairness much of what explains their action is wrapped up in the Redemption series (in the case of Liara anyway). I was glad to see the tie ins, and was not really let down at all.
5) The game would hardly be fun if they said "HEY! You played Mass Effect 1. Therefore, you have master skills, are unbeatable, and get to watch Mass Effect 2" They give a bonus for playing ME1, and without having set up your playthrough to be imported you are stuck with the story that ME2 decided happened.
6) If you foul it up bad enough, no one survives the suicide mission. The idea is to reward players for getting the right upgrades, knowing how to delegate and for forming a cohesive and loyal team. If you do it right you live, yay! If you do it wrong you die, boo! As the concept of a game that you can complete and still die completing is fairly unique these days, so I at least like the concept. Also the boss in ME1 was not really any more difficult to defeat. As for the specifics of the boss and why it is the way it is, try to follow the story better.
That was the love, now for the hate.
I am inclined to agree on the side missions and the minor ties ins from ME1.
In ME1 I often found myself...well frankly giving a shit about the side quests and the choices I had to make in them. However, in ME2 I rarely feel a shred of remorse for making a renegade decision that, lets say, blows up a bunch of orphanages. The sub stories fall face first into a big pile of spunk.
For the cities that implied sense of bigness works wonders, but on the side mission planets, we are given NO context of the planet outside of the bittie little map that we are thrust onto.
My major problem is the lack of development in the side missions, as well as the fact that the sole difference in effect from some of the choices you make in ME1 is whether or not you get a letter from them, or run into them standing about on a space station looking bored.
In fairness, I understand why. They game is very big as is. But then why bother.
What I would ideally like to see is either the augmentation of the tie ins, or scrapping them altogether. I would like to see some emotional investment going into the side quests, so that I actually care about the data I grab from some merc base.
Also since the Steam version comes with a Key for the Cerberus Network, I got to play the firewalker DLC. THAT IS A GOOD VEHICLE FOR DRIVING SECTIONS.
In summary, I feel that ME2 is an improvement over ME1, and I loved/love ME1. However, some of the things they tried, or more precisely didn't, fell flat. The current direction still isn't quite it. But the ?it? that I am describing nears perfection whereas for other game franchises "it" refers to not being awful.
The problem is that ME1 set up an endless well of possibilities. And while BioWare tapped that well for some ideas, they seem to have misses a few, and scrapped some good ones to make room. It is natural to feel let down by this, and to be concerned, because if modern trilogies are anything they are soul crushing on the third iteration. Still, for a franchise this enjoyable I hold out hope that BioWare will find a way to remedy their flaws, and to fit all their ideas into 1 cohesive game. Yes it has problems, and no it isn't wrong to expect a game to be perfect, but yes it is wrong to say that BioWare isn't trying.
