I just downloaded Zen Pinball 3D and its really good, nice 3D effect too. Comes with 4 tables and online leaderboards. Should keep me busy till RE & MGS come out next month.
That's pretty much my Go-To game when I'm just messing around. LOVE the Medieval table "Excalibur"!
"Excalibur... shows you the way!"
"Are you a Knight... or merely a squire?"
"Now behold the powerful magic... of the Great Merlin... MULTIBALL!"
Mighty Switch Force rocks, too.
Oh, and PushMo.
And Ketzal's Corridors.
These games are awesome and cheap!
