Fun game but it glitched on me while doing the buccaneer quest requiring travel from Axel to LaVille. Upon reaching LaVille I tried to battle the city. Instead of performing the battle I got a message saying something about my choosing not to attack. And instead of entering the city my wagon continued to travel but the mini-map couldn't track it (-300.9 hours to destination).
It could do with some polish, but I liked it. 4/5 (-1 for IA and the overly powerful planetary missile). Devastator ship would be better suited as a stationary weapons platform.
Two suggestions: 1) in the help section tell players HOW they earn more cards [by gaining xp and playing other heros]. And 2) an indicator that states when new cards have been awarded. Great game. 5/5
