Great game.
I've been bored by some open world ubisoft games, but this is a galaxy of fun.
I think of it like this- Red Dead 1 was not as good as you remember it, because Red Dead 2 was a vastly improved upon sequel that is what really sticks in you memory. If you go back to the original, you'll see what I mean.
Outlaws deserves the chance for a follow up, and the team at Massive would certainly live up to expectations imo.
Outlaws is a great Space Western, with multiple environments. The skills you can learn add plenty of depth to the stealth and blaster play.
A sequel would undoubtedly address the hater issues, and deepen the immersion.
The soundtrack is authentic, and even adds a Firefly flavour to proceedings, which I love. The voice talent in Outlaws is top notch, maybe part 2 could even attract some original voice cast...
