When it comes to biking games, there aren't a lot of options on current-generation hardware. Until just recently, basically anyone that wanted to play a biking game would need to check out a game in the Trials series, and while Trials is plenty fun, some may be looking for something a little different. Lonely Mountains: Downhill is a decent alternative to Trials that's just different enough to standout on its own.
Whereas the Trials games are known for their intense tracks, platforming challenges, and stiff difficulty, Lonely Mountains: Downhill is much calmer and laidback. The games play similarly in that they're checkpoint-based and players have to be very careful to avoid wrecking their bikes, but Lonely Mountains puts an emphasis on actually riding a bike instead of just doing ridiculous jumps and stunts.
