How to say when you're doing a specific thing?


I'm still a little confused on the nuances of the の particle. For example,
let's say "I played Dota 2." Would that be

> "Dota 2 **の** ゲームをしました。"




I understand your tendency to want to use `の` in this case. However when you
want to introduce the name of something, you should use `という`. (assuming you
are introducing it for the first time). So you could say, `Dota2というゲームをしました。`
If the game is mutually understood you can just say `Dota2をしました。`
