BlackBerry acquired ScoreLoop some time ago and it seemed like it was going to be a great tool for cross-platform multiplayer gaming. We haven’t heard much from ScoreLoop since the launch of the ScoreLoop SDK 1.0 which launched about a year and a half ago. There have been some minor updates but it seems to be pretty lacking, especially in terms of dealing with multiplayer gaming. BlackBerry game developers should therefore take a look at Photon Server by Exit Games. It’s a really robust platform, albeit not cheap, that should give you the necessary tools to run a scalable multiplayer game on BlackBerry and any other platform you choose.
