I think it's great you started this thread. I previously owned a 9900 before I switched to a skinny bold (9790) and a lot of the games (looking at you Gameloft & EA) are incompatible with my new device. Games like N.O.V.A. and NFS Shift cost a bomb and are now unavailable or only downloadable as a separate application to my previous purchases. But of a gutter.
The playbook is picking up momentum again but we need some more support to save the inconvenience of side-loading and emulators. The sooner the wider game publishing industry recognizes BB OS as a lucrative platform the better.
