Lizard Dude, as always, has impeccable taste in games. I don't feel bad recommending Blaster Master as hard as Raiden Fighters Aces, Solomon's Key, or Space Invaders Extreme 2. (Note: Games not listed in order of quality.)
Bejeweled Twist is easily one of the most engaging and enjoyable match-3 games I've ever played, and those of you with DSis should certainly buy it on DSiWare.
Any idea what's on the Konami Classics collections? Are they just collections of games previously released on XBLA like usual?
