One game that I’ve been getting into recently is Beat Rider for iPhone/iPod touch. Here’s the iTunes link. While it’s somewhat a competitor to Tapulous’ Tap Tap Revenge 2, since both make you tap to music, it has an advantage and/or disadvantage: You can use what ever song you want. Because of this freedom, the gameplay resulting from songs isn’t always very good. On the other hand, there are some songs that shine. Try out Coldplay’s Viva La Vida. It works surprisingly well.
Another game that might be worth checking out is Chris Sawyer’s Locomotion for Windows. It’s not new but it’s pretty fun, if a bit demanding at times. You connect with trains, boats, road vehicles, planes and trams, cities, factories and resources to make money. It’s not bad for $10. Plus it’s from the guy who brought you RollerCoaster Tycoon.
