Let's talk about Dota 2, shall we?
The official description from the all-knowing Wikipedia says
Trailer:The game consists of session-based online multiplayer activity, with the primary objective of each match being for the teams to destroy their opposing team's fortified stronghold. Each player controls a player character called a "hero", who is given the responsibility of participating in team combat, which generally takes place along a series of lanes that connect their opposing bases, lined with defensive towers. The gameplay elements are largely incorporated from Defense of the Ancients, with the game's lead designer, "IceFrog", being the longest-serving and current developer of the Warcraft III mod.
It's apparently been in active beta for several months, judging by the number of YouTube videos. They've also held a major tournament already.
Who's playing it? Who's interested in playing it? There was a post in the FNF forum looking for players, but I haven't heard much mention of it otherwise.
When I saw this as Valve's next big upcoming game, I was puzzled. I am unashamed to say I'm a Valve fanboy. They've never made a game I didn't enjoy. But they've also never done a game anything like this. A squad-based, top-down, action/fantasy RPG based on a World Of Warcraft mod is pretty far from Half Life, Portal, and Left 4 Dead.
I admit that this doesn't look like my type of game. But... it's Valve. I have an enormous amount of faith in them, and not just because they make "fun" games. The effort, artistry, and craftsmanship they put into their work makes their games special. Architects designed Half-Life 2's City 17. Wheatley from Portal 2 was animated by an authentic Muppeteer. Things like that are what (to me) make Valve games stand apart.
So... let's talk about it.
