It took them 5 to 6 years to port the original DotA in its entirety to the Source Engine. They added the first major changes to the original game only a few weeks ago. Everything else was just copying Heroes, items and features from a really old mod. Don't get me wrong, I like and regularly play DotA2, but it's nothing groundbreaking.

I stand by what I said. The Orange Box was the last great hurrah for Valve gaming.

As an avid player of dota 2, I think your underestimating how much invisible work goes into dota 2 itself. It's probably the best MOBA in the market as far as game design.

Dota 2 is pretty much the only game that can keep my attention, everything else just falls by the wayside after a while.

You play DotA and you are claiming that 7.00 was the first major change? You are having a laugh. The game has made massive strides in UX, gameplay and graphics, all while also pushing a professional scene that is now running three multi-million dollar tournaments a year in a scene of nearly-constant tournaments around the game.

Also, Portal 2 was an incredibly polished, fun game.
