Incompatible WP7 Games
Nearly all Xbox games from the WP7 Marketplace (full list here) are also available on WP8 except for the following:
Big Buck Hunter Pro
Fable Coin Golf
Full House Poker
Hasta La Muerte
OMG: Our Manic Game
Pac-Man Kart Rally
Pool Pro Online 3
Rabbids Go Phone
Sid Meier's Pirates
Splinter Cell Conviction
The Oregon Trail
Zombie Attack 2: Second Wave
* Fruit Ninja has been updated to the most recent version (i.e. identical to Windows 8) for WP8 and therefore the WP7 is longer available. However if you still have the original on your handset the two versions will work alongside each other and the achievements are also stackable.
Note: WP7 titles exclusive to Nokia are also available on Nokia WP8 handsets apart from the games mentioned above.
Thanks to everyone for this info.
