So with Batman Arkham City just around the corner, I have noticed that there are a plethora of various Pre-order bonuses, such as the costumes that you have no doubt seen, and are raging if you live the US as they haven't announced anything about them yet :P
There is also a 'Robin edition' from GAME.co.uk and a 'Joker edition' from Tesco (Supermarket chain in the UK if you didn't know :P ) Both of these contain unique challenge maps as Robin, or the Joker respectively and I believe you also get to just totally play the game as Robin as well if you want.
So my question to you is which one do you think would me more beneficial to purchase?
Also what are your opinions on games having this many Pre-order bonuses and editions across so many retailers, that you can never really hope to have them all?
