Simply the best game I have played in a long time.
As the game starts you can either enter a profile or create a new one. If you create a new profile you will be given the option to customize your hero somewhat. You can play as male or female and alter the facial appearance and hair styles. You can change the first name but not the last name of your character. As you progress in the missions you gain experience and levels. You spend points upon level-up to fine tune your character's skills as well as your group members skills. Various merchants sell upgrades, armor and weapons that can be purchased with credits from mission rewards.
The graphics are decent however I had trouble with dynamic shadows being too pixelated and thus had to turn it off. Also some sounds were either too loud or not loud enough. Volume levels tended to be uneven. I wear headphones so this was a minor issue but nothing that really took away from the game experience.
This game to me is most like Oblivion in Space. This game has a lot of potential for future expansions. This could open a whole new Franchise for BioWare.
