Of the three games in this series I'd rate them:
1) Pinbot
2) Jack*bot
3) Just about any other pinball game
4) Bride of Pinbot
The reason I'm putting the first Pinbot game in the lead has to do with the "limited" ruleset that makes the entire layout work. Both Pinbot and Jack*bot suffer from a bad case of right-flipper-itis. There really is only one shot from the left flipper and that's to the advance planet standup (and it's a death shot!). Pinbot's scoring system is better balanced than Jack*bot's. The gameplay puts real value on the skillshot, where as in Jack*bot, it's not worth that much. On the other hand, Jack*bot's gambling theme is realized incredibly well. Now there are players that LOVE the wizard mode and while I think it's well done, reaching your wizard mode in less than less than 10 shots, does not endear it to me.
Bride of pinbot is a 1 shot wonder and that's a damn shame. It could of and should have been more of a game. I'd love to see what the Dutch are doing with this table. I am very excited at the prospect of an improved ruleset, but even then... we shall have to see what they come up with in good time.
