The people who have seen the gameplay footage of DotA 2 are unfamiliar with the in-game Lobby menu of DotA 2. Not long ago, some screenshots of DotA 2 menu were presented on a discussion forum. The DotA 2 lobby menu is very similar to Heroes of Newerth but it looks unfinished. It has the option of Tournament, Matchmaking, Patrice & Tutorial mode.
Valve has optimized Steam connection settings for DotA 2 so, players with slow internet connections will have minimum lag/delay problems while playing. DotA 2 will have servers in every continent to provide lag-less experience to users. You’ll have option to join official DotA 2 servers or create your own. More updates to come.
