Mir is the only REAL-TIME MMORPG i've ever played.
In that regard I mean where the player can physically dodge an attack by moving from the spot where that attack is being aimed, in the slight delay between the client-server communication.
This is the key to the face paced gameplay and the feeling of being in total control of the character, you can run onto a spot where a wizards gunna cast Meteor, or you can dash off a spot where a flamefield is about to be cast.
Any 3D Game, they'd target you with Meteor, and it'd hit based on some stastistical calculation ... In Mir ... You can avoid attacks entirely with good movement. no 3D Game has been able to do this as far as i've seen.
Player has total control and nothing is impossible provided you can outmanuevre another mob or player while still landing your attacks...
Ahhh, great stuff...
