A fun rpg, but there are some areas that need improvement.
However, there are several mechanics that need to be improved. For one, there's no need for the player to drive around the Mako on the planets, especially since 90% of every planet is nothing but mountainous terrain. Driving from place to place is a chore; I want to just pick the target site and jump right into the action.
I also don't like how there's only a few "dungeon" designs on various worlds. If you explore various planets, you'll soon realize you're running through the same buildings, just with different furniture and enemies.
Also, you'll soon realize that the sniper rifle is useless. There's no limit on the range of weapons, so as soon as you fire on an enemy, they all fire at you and hit you hard. The computer opponents have near perfect aim and the sniper rifle cannot kill in one hit, so using it puts you in a situation where you'll likely die before you get off a second shot.
Overall, it's a great game and you should definitely play it. If the developers spent a little more time polishing the game, it could have been a masterpiece.
