I've actually never really gotten into Wario, period. Way back when I got my Game Boy Color, I got SMB Deluxe and Wario Land 3, and soon ended up trading WL3 for another SMB DX so my brother and I could use the 2-player mode. WL3 just didn't appeal to me for some reason. Perhaps it was the lifeless gameplay.
I did play Mega Party Game$ at a friend's house once, out of state. It took me a while to figure out, since I didn't really know what Wario Ware was about, but it was pretty fun after that. Still, "fun" isn't enough to make a game for me - I'm interested mostly in games with actual plots. By that, I mean an actual problem or action that needs to be taken and not "Wario gets an idea and makes a video game and now you're playing it".
