Trace Memory 2
Haven't heard of this before, maybe I'll look into it.
I own both of the Punch-Out!! games but I've no idea why. The game is sort of like a cross between a fighter and a puzzle game, since each opponent has some sort of trick(s) to beating them, but I don't like fighters and that aspect really turns me off. I didn't really like Mario Strikers either, another series developed by the same company.
Sin & Punishment 2
I'm not really into shoot-em-ups. I kicked some broomsticks in Contra back in the day but that was about the only shooter I've liked. Gradius and R-Type just aren't my thing. I'll still probably watch over this though as it's a sequel to an N64 game, and N64 > mops. And I love mops.
Wii Sports Resort
I don't know much about this but it seems a bit unimaginative, like it has the Wii Sports name just to sell it. I also couldn't possibly express how much I despise the Wii Motion+ accessory, at least not without being seen as a huge troll.
Endless Ocean 2
The first one was magical... and I actually forgot that it was released in 2008. That was a good game to start the year with. I'll be watching to see how this turns out (and if it's released outside Japan).
New Play Control! Pikmin
I rented this back in the day just to get the Olimar trophy in SSBMelee, so I never played past the first save point. Does that make me a bad person? If so, it's time I remedy that by giving the game another chance. Having Wii controls may make the game better... but I guess I won't know that as I have no comparison...
New Play Control! Mario Power Tennis
I skipped over the original because it doesn't have Toad and Birdo as playable characters. Yes really. I wouldn't mind having a good Tennis game on Wii though so I'm going to see how this one turns out.
That's all I've heard of from Nintendo for 2009. The year just started so there's probably something else on the way which hasn't been announced yet. Still, I can't tell what a gem is until I've played it; the game of 2008 I thought I'd like was the game I despised, and the one I'd thought I would dislike is the one I became enamoured with. I'm just going to wait and see.
