Blizzard rendered a large swath of StarCraft II
content free to play yesterday via a patch that greatly expands the scope of the free, downloadable StarCraft II: Starter Edition
The StarCraft II Patch 2.1 notes
detail a host of additions and gameplay tweaks to Blizzard's sci-fi RTS, chief among them being the news that all races, custom games and the entire Starcraft II
Arcade are now available to all StarCraft II: Starter Edition
Given that the Arcade is essentially a curated storehouse of player- and Blizzard-made StarCraft II
mods, Patch 2.1 basically makes a ton of user-generated StarCraft II
content free to play and will likely cause the StarCraft II
modding community to swell significantly.
Prior to Patch 2.1, Starter Edition players could only play Blizzard-made mods in the Arcade and were limited to playing as Terran in custom games vs. AI.
Players must still log into Battle.net (and remain online at all times) to play the Starter Edition, and you still need to purchase the full game to play the campaign or take part in multiplayer matchmaking.
