DOTA 2? Wow.
It actually sounds like an amazing game, with infinite strategy and meta games to play (though perhaps it all comes down to one hero countering another, I dunno). I believe in PvP games, you 'draft' your team one at a time and there is even a lot of strategy in which heroes you pick at that stage and which you pick to counter your opponents' pick, or you end up with an unbalanced team, or one with a fatal flaw that will be exposed during the game.
I have to say the language used in describing games is pretty incomprehensible, and I don't think I really want to know what is going on. It's kind of like Blood Bowl in that regard for me - I'm afraid of getting too close.
I suppose the main issue with the game is that the players are complete assholes, to a man
Obviously that is not 100% true, but it sounds like it comes close.
So, are you hooked!? I am guessing you will turn it on just to have another go, and then...
