I feel like I have pinball's best kept secrets in T3 and Jackbot. The latter is Pinbot but with much better rules and sound, I don't see how it isn't more desirable with the praises people sing for Pinbot.

T3 has a very fast, smooth shooting layout and tons of great features. Yes, it's shallow and on the easier side (though I have mine setup like a bastard currently that makes it very risky locking balls for multiball), but that doesn't stop it from being a great game. Tons of fun and nails the theme. Far superior to T2 in every respect but commands the same price as one??? No idea why.
