I did - it's mostly a straight-up brawler. Very simple. I am enjoying it but I wouldn't necessarily recommend it to any hardcore gamers.
Basically you walk through an area beating up Manhunters. After each small area you reach a GL symbol and you "fly" (uncontrolled) to another area. In the main missions you don't fly though you can do jumping attacks that keep you air born for a limited time.
The only real annoyance to me is the relatively small fighting areas. You can see a lot of action going on across OA but you basically hop from one small "island" to another, and only after you defeat all the enemies or accomplish a specific goal. There is no roaming of any kind.
I've come across one flying mission, which is on a track while you shoot projectiles at enemies.
Combat on the regular levels is fun due to the variety of constructs and the ease of the controls. As you earn points you can purchase new constructs and upgrades. You also assign the new constructs to your preferred buttons when you buy them, which I like.
There's not a huge variety of enemies. Manhunters, Manhunters that shoot, Manhunters that ride little ski-ship things, Manhunters with shields and the occasional big-ass Manhunter.
It's repetitive. But as a casual gamer and big GL fan I don't mind that too much.
Ryan Reynolds voices Hal but I think that's it for the movie cast. The voice actors are good, though. Your ring gives you instructions and info and Sinestro and Kilowog yell at you to hurry up via ring-radio.
It's your run-of-the-mill move game, I guess. The pros are a short learning curve and well animated, fun fights. The cons are a very simple story (Manhunters attack OA - get 'em!) and repetitive action (though, admittedly, I am only about an hour into it).
I looked for this at Target this morning and they had none. I got the only copy at my Gamestop because, they said, no one at all pre-ordered. I don't know if that means the production numbers will be low or just that it will be on clearance within a month. Just some food for thought.
