We are already two generations beyond the Wii and I am still getting caught up on all the games I've been wanting to play for years.
Red Steel 2 was the first big title to take advantage of the Wii Motion Plus controller. For some reason, the prospect of a motion controlled sword fighting game was always a big thing. I think Red Steel 2 comes close to fulfilling that nerd dream. It still is a bit of a waggle freak-out during hectic fights, but, when it's focused, the motion controls work very well. This is a massive improvement on the previous game in the series.
I'm not even sure why this had to be a sequel. The plot and setting have no perceivable connection with the gangster themed original. This game takes place in a steampunk-ish, old-west-but-Japanese setting. It feels a whole lot like Borderlands in tone and art style. After the first few wacky cut-scenes I realized that there was not going to be any sort of coherent narrative. Something about a sword and a guy who wants your sword? Whatever. What matters here is that the game is fun.
As I have stated elsewhere on this Web site, the Wii's controls are really good when it comes to console FPSs. The movement, shooting and sword controls very natural. Sure the sword strikes could have probably been bound to buttons, but the motions make sense. There should have been dozen of games like this released for the Wii, too bad this came so late in its life-cycle.
