The first did have it's technical hitches, but in the end it was another Bioware masterpiece that delivered an outstanding gaming experience IMO.

For Mass Effect 2 Bioware is not only looking to slightly improve upon the first, but rather they are making huge improvements on the first which is great for us, the gamer. From the vid you can see an improved targeting system, a new biotic power, the ability to give out commands in real time to your squadmates instead of pausing the action, and without a doubt a nicer looking game. Space exploration won't just be an open map where you move your cursor around to the next planet and land, as you will now have the ability to scan each planet in depth, as well as rotate the planet and find your landing zone of choice. Oh, and once again your choices will have a direct impact on how the game will end for you with (Spoiler Alert) your choices even leading to your Shepherd dying permanently.
