Brawl, I thought, was rather disappointing. It got boring a lot faster than Melee did.
For the Wii, all I have is Lego Star Wars: The Complete Saga (which has to be one of the most awesome Star Wars games ever), Pokemon Battle Revolution (which was surprisingly fun), Metroid Prime 3 (I bought a Wii for this, primarily...) and Resident Evil 4 (because I'd played it for Gamecube and I wanted my own copy)
I'm planning on getting Tomb Raider Anniversary and Underworld, because Lara Croft is making a return to form, but I'm mostly a handheld person now.
Although that said, I DID buy an Xbox360 today...
