E3 Coverage - Mass Effect
This is an RPG where the galaxy is your playground. The game world is a huge scale with a sleek and futuristic look. You can play as Commander Shepard or develop your own fully customizable character. There is a lot of walking around and interacting with NPCs. Everything is very fluid and the character modelling is excellent. There's an innovative dialogue system where you pick the basics of what your character should say and then he says something like what you selected but with more detail.
One thing that's very cool is that you can look at the galaxy map, pick a planet, then go directly to the planet and explore it. The game is sort of like Star Wars Knights of the Old Republic in terms of dynamics but it is more open ended. It's been in development for two years and really looks great. It's the first of three games in a series and they promise a lot of downloadable content.
