Yeah, I can't fault the game on a technical level. It looked and sounded great and I don't remember coming across any bugs, glitches or crashes. Seemed really well made, for consoles anyway.
Aside from the tank bits, the game is excellent. Even towards the end, I wouldn't say I accepted to the tank bits but I found them less irritating. I wasn't keen on The Riddler, but I didn't think much of those bits in Arkham City anyway, so there's nowt new there.
Story was excellent though. Looking back, I think I preferred this story to Arkham City. Definitely will play it through again at some point.
