IMO, the beta was great.
Tight controls.
Awesome graphics
Lots of weapons
Level up classes
Huge bosses
Co-Op quests
Co-op single player
Vehicles / with & without weapons
Smart AI
I would want to see in the final game,
- Lots of planets to explore
- Co-op available as an option throughout the entire game
- More weather effects. Snow storms, Blizzards, Sands storms, Huge rain down pours.
