I started playing it on Thursday and it's pretty MEH so far.
I'm about two levels in and the combat isn't too different. You pretty much use the same battle tactics (strafing with your rocket cannon) and vehicle mode is only good for making quick getaways.
The major turnoff was making this a prequel. I was looking foward to seeing the antics aboard the Gekko-Go with Holland, Talho, and crew. Intoducing these SOF wannabee is somewhat of a letdown.
Yet another letdown of a popular licensed anime down the drain by Bandai.
