I agree with you, CK. Maybe the guy that wrote that was too stupid to find the speed settings?!
Sure, games take a bit longer with OP2, but that doesn't mean it can't be fun to play.
OP2 is nice because it doesn't have a pop limit, unlike other games. (You could theoretically have 1000's of tanks)
Also, the game is sort of frustrating when you first start playing... It takes a lot longer than 35 hours to learn the game well. Once you know for example, the researches, etc. you can really go.
