NWN 2 had both better graphics and a better story than NWN. I expect that will be the case with ME 2. And while the graphics look better, they've cut down in other areas. No driving your Mako around empty planets anymore and companions on have two outfits, for example.
The systems themselves have been improved. Companions know to equip themselves with a best version of whatever weapon you've given to them, so there's no shuffling through all ten inventories to make sure everyone is up to snuff. I realize some people will consider getting rid of most of the buying and selling of equipment as dumbing down, but I was one of the people who thought it odd that my Alliance Marine/SPECTRE operative was buying weapons in the first place.
I like the bit at the beginning. It should be interesting to see Miranda, the authority loving scientist, vs Subject Zero, the authority hating science experiment.
