Weird. I didn't edit anything, so I've no idea where it went. Here it is again: http://access.jibc.bc.ca/avalancheFirstResponse/index.htm

It's not exactly a game, but the Canadian Avalanche Centre has an online course with some route-finding activities. They give you weather conditions and avy hazards, and you plot good lines up and down the mountains. All in all it's a decent resource. No replacement for a hands-on avy course, but it's a good start or refresher.
