It's not great, but it's not really bad either. I'd say the game is worth about $30. The storyline is typical japanese bullshit fed into an animetron and turned up to 450 degrees. I'm glad they've started using real footage though, I'm much more interested in black and white video clips from the history channel than hearing cheesy dialogue about someones shadowy past. I digress. The gameplay is what sold me, I played the demo somewhat extensively. If you're a fan of tactical RPG's then you'll probably enjoy OD. Adding guns to the mix makes it an awesome experience, balancing the gunplay with ammo usage and a very strange "cover" system keeps it from getting dull. The cover system works very weird, when you go into cover mode you'll get the option to move with someone, shoot an enemy that moves or attacks, or shoot at the same target as someone else. This means that you can shoot multiple bad guys per turn with one character, the downside being that you waste more ammo since these shots aren't as powerful as a normal shot.
The game's very redundant, everyone you can recruit is fucking useless, and I'll never forgive a game that forces a game over when a main character dies in a tactical RPG, even if it is the norm. So I'm kind of on the fence, and that's why I haven't beaten the shit out of the game, I'm looking forward to playing multiplayer though, I wonder how that's going to work.
