Quoted from Bublehead:
The two titles are hard to compare in my opinion. I play in the APPL (Az Pinball Players League) and I get to see what all the wizards keep in their collections in and around Phoenix Arizona. Both of these titles are banes in the wizard world. Of the 20 to 30 collections I have played on, MB and Congo are NOT titles that hang around in wizards collections. Both are fun, both have their strengths, and most will put Congo above MB on which is more challenging, but almost all agree, these are not keepers in most wizards lineups and are usually transient. Everyone loves to play MB, especially getting to the final MoR Bash em up, and when you have guests it is always fun to show off by getting to that mode, which is not that hard. Getting a high score, all the instruments, etc... is where wizards have to challenge themselves. RTU is harder to get, and why I like AFM more and why it is in most wizards collections instead of MB. Congo is a sleeper title, and some players love it when they see it in tournament play, but almost all roll their eyes when MB is in the lineup, usually due to the massively long game times it brings to a competition. You should ask yourself which do you prefer more, a challenging, fun game or an impressive piece of playable art? Because MBrLE is just that... a gorgeous feast for the eyes, ears, and flipper fingers.
Lots of these types in your league?
