Look, I always go by IGNs reviews, and they seem quite keen with RED STEEL, except ultimately the controllers ruin the experience. Apart from the control issue, they seemed rather impressed with the game as a whole, and I think if you just try it out and attempt to get used to the slow turning rate (this is really the only complaint) or pray that Ubisoft brings out a firmware update, then you will be hapy you made your purchase, if not sell it on ebay, or return it to the shop you purchased it from for one of the many other great Wii titles...
Reviewers give their opinion, to help influence our purchases, but it is us who make the final decision, and really, they too are human, they can find faults and can have problems with a system that doesnt HAVE to apply to us, its just their opinion, and they are throwing it out there.
I have no doubt the aiming isnt quite as smooth as a keyboard/mouse setup, but learning is all part of the fun and I personally cant wait to have a try.
