Avengers Pro
24 Features
2 x ramps,
4 x hulk drop targets
4 x thor targets
3 x tesseract targets
1 x hulk smash targets
3 x shield agent targets
1 x spinner
1 x spinning cosmic cube,
1 x hulk target figure
1 x magnet feature
1 x combined ball diverter
1 x kick out

So interestingly it has a total of 24 features which is very similar to the Iron Man which is enough for a good gaming experience, as for the Avengers LE having just a couple more so still lots to do on the Pro and LE.

Can anyone else add some details of X-men, AC/DC and Tron as would be interesting to compare.
