>>7136021523 came out when everyone had abandoned game editor. If 3 had open sourced and released a user-friendly and powerful editor then it would have been an amazing game cause the art style & renderer was very impressive for its time, only rivaled by Isolation & Battlefront which released 4-5 years later.
However yes 2010 was indeed one of the shortest fucking game I have ever played rivaling Colonial Marines' in shortness.
2-3 hours for the Marine & Predator campaign each AS A FIRST TIMER. and 1 hour with the Alien campaign AS A FIRST TIMER.
It indeed was a tech demo. But unlike Crysis, Crysis actually had a game and proper multiplayer to play and a bunch of other features. Everyone else copied Crysis without understanding that the guy in an armored suit isn't really slow, he's just heavy, but not slow. Everyone didn't get the memo on making a creature feel heavy yet fast.
