Excellent first post (I haven't seen you around before). You're right - cricket is far too complicated to ever have a completely accurate videogame rendition of the sport, but from what I've heard and played, this is easily the closest we've ever come to it as yet. For example, if the AI bombs along at 10 runs per over, so what? You'll probably also bomb along at 10 runs an over! It's good, competitive cricket, just with run-rates that are maybe a bit too high. As long as every ball doesn't disappear for six like with BLIC 2007, it doesn't matter.
For me, I want this game to be hugely successful and I want Transmission to stand by their game, because it is worth it, and deliver patches to iron out certain unacceptable problems (it has to be said), such as medium fast bowlers not being able to break 80mph, the borked edges (in the demo, at least) and the awful runout bug as seen in the demo (although many say it has been improved in the game).
Which format are you getting it on? I have preordered it on PC and am expecting it Friday morning. Just in time for the Test, as it happens.
