One of if not the best game this generation so far.
The levels are so much more detailed and fell so much more alive. There's almost too much to do. When I first started playing I was a bit overwhelmed with all I could do.
The graphics are great, very little slowdown or texture pop-in. I could only notice texture pop-in during 2-3 in-engine cutscenes, and even then it was split-seconds.
Action is much more fluid this time around and makes for a better overall game.
Only a few negatives that keep it from getting a perfect 10 in my book.
It is a bit buggy. I've had to load from the autosaves several times while on the Normandy because the galaxy map glitched. I've had to reload from autosaves once or twice during missions because Commander Shepard suddenly learned how to float in the air, but couldn't walk.
Inventory is a bit too simplified. I miss being able to buy guns and upgrades. Sure there is the tech research, but it isn't as good. Hopefully in ME3 they will have a mix of simplicity in ME2 and the depth of ME.
Loading times. They are by no means bad, but they are still there.
Too much to do. I don't know how I'll ever be able to do everything in this game. When it comes to romantic relationships alone, there's so many options.lol
It's so hard to be bad. My first time around I tried to be a renegade, but I felt bad, kind of like Fable II.lol Maybe I'm just a softy.lol
Overall, it's a game I'll be playing for a long time. It'll definitely hold me over till Alan Wake, Splinter Cell: Conviction, Halo Reach, etc. I'm now on my 2nd Commander Shepard from ME1. I'll probably do full renegade with this one (My first Shepard was full paragon). And I'll probably make a 3rd character in ME2.
