Just in case you were too lazy to read Samit's article (and you should feel bad if you were, because he puts a lot of time into them), BattleForge is on online RTS that incorporates the idea of using tabletop gaming cards to represent the game's different types of resources. Now, on to the multiplayer!
The first round of online we played was pretty confusing. Having never ever played the game, it was kind of difficult to just jump right in and know what you were doing. Destructoid thinks others there were having the same issues, so it was suggested that we all try out the tutorial if they wanted to. That was a very good suggestion.
