Congrats on finishing! Looking forward to trying it soon.
As for what genre would be good, I'd definitely be down for a good managment/ "God" game. I'm speaking something in the vein of Sim City, Tropico, Anno, or even MLaaK type of game where you build up your place and manage various resources.
The Nintendo Channel says I've put in nearly a hundred hours into MLaaK, and an extra 30 into Anno, so another WiiWare game in that genre would be right up my alley. Just make sure not to have the tedious interface that MLaaK did, because that kills me.
I'm pretty sure I'm in the minority here though.
