Linux users are often given the cold shoulder by gaming companies, and have to resort to running emulators to play most titles. There are however numerous examples of successful mainstream titles that have found a happy home with Linux gamers.
Heroes of Newerth
Perhaps the first recent title that will pop into the mind of Linux lovers is the upcoming Heroes of Newerth (HoN). The action RPG from S2 games was inspired by the wildly popular WarCraft 3 custom map, Defence of the Ancients, and is currently in beta testing. A Linux build supporting both 32 and 64 bit binaries is available.
Another action RPG from S2 Games – it is free to download and play, with an option to upgrade to a prime account for US$9.99 (±R75). The prime account gives the player the option to play as a battlefield commander, two additional inventory slots, and the ability to view statistics among other benefits. Currently has a 75/100 score on Metacritic.com.
