I like T2 but if you can't dial in your skulls shot and cannon shot, you're gonna have a bad time. It's a great theme but the game doesn't have as much going on as some of the others on your list.
Dirty Harry is the only machine I own, so I've played it quite a bit. I think it's a lot better than people seem to give it credit for. There are a few sets of modes to work through. The magnum is fun to use and integrated into the game quite well. The left ramp shop is really fun to hit. The multiball is pretty good in that the left ramp is the super jackpot, though if you get balls trapped on the left flipper and have your left loop shot and left ramp shot dialed in, you can really rack up the points. I don't feel like this is as easy as it may seem.
