Great role-playing game, but not a very good third person shooter.
Once you get past the combat system, the game is great. There are incentives for immersing yourself in the game's lore, all-around good voice acting and FULL SPEECH! The dialog system is effective - you only read a short summary, decide among the choices and your character engages in an almost fully realized conversation! Almost like an interactive movie.
Another gripe about the game is that the main quest feels too short. The side quests are fun to get you traveling to other planets/systems/clusters, but I think there's more sidequest than main-quest to the game.
