I bought my first Wii a couple of weeks ago and am very impressed with it so far. Currently I am enjoying some Sega Gunblade NY action...very nice on a 28" 4:3 CRT via RGB SCART.
Double Strike/240p looking good on Shinobi.
I've also managed to connect it an old school PC CRT and 480p looks stunning...here's A Boy & His Blob. Looks better than on my friend's Wii U connected to his 43" HDTV. Then again this is a 'native resolution' screen.
Only downside is my Logic 3 Gamecube Arcade Sticks are incompatible with the Wii (known problem)!
