Have you ever played LUXOR? I haven't, but according to Pocket Gamer, over 40 million people have! Yikes! I guess casual gamers really ARE an important demographic for companies to target. Well, it looks like two casual games are coming to hardcore PSP owners: Luxor: Wrath of Set and Platypus. Luxor is one of those marble games, akin to DS's Magnetica. Platypus looks to mesh the shooting action of Gradius with the classic look of Clayfighter.
Both games are coming to the US in November for the "mass-market" price of $30.
[Update 1: Yes, made a boo-boo on the names. And Platypus is a weird word to spell.]
