Played some more games. Here's what I like, in the order that I like it.
Mercury Meltdown Revolution is a fantastic budget game. Plays like Super Monkey Ball, but with a lot of twists and differences. I highly recommend it. $20 in stores. Though most the music is merely okay, some is even remix worthy. Particularly Bio Lab stage 16. Wonderful song, I may rip it so you can have a listen.
Also, Geometry Wars Galaxies is made of win. You can even send DS demos from the Wii. It's a fully fleshed out game with 64 stages instead of one .. and other mechanics like Geoms (money for unlockables, also for a new multiplier system) and drones (a little invulnerable box that helps you out). It plays great on the Wii, and if you don't like IR aiming you can dual-analog it with the classic controller. There's 2P Co-op and Vs, and it also includes the original XBLA version. The difficulty is varied, some stages are nice and hard I have no complaints about this game.
Soul Calibur Legends is mediocre. It's a hack-and-slash adventure, no more, no less. It doesn't have the depth, or even as good a story as the SC fighting games. There are 7 playable characters, including the surprise character ( Lloyd from Tales of Symphonia) who happens to be my favorite. Everything about the game reeks of poor design, but it's decent for a hack-and-slash beat-em-up style 3D game. The graphics look great for a Wii game.
Cruis'n is outright terrible. AVOID AT ALL COSTS. It brings shame to what was once a good arcade game series.
