You guys know the mmo-rts game Defense of the Ancients, this game is know globally in the entire world. They even have tournaments with the participant of many countries. Dota is expanding to Dota 2 with Valve as the publisher. In the terms of gameplay, i personally prefer dota 1 because i am used to dota 1 but dota 2 offers new and nice quality of graphics. But dota 2 has flashy images that can make my eyes hurt and sometimes suprising sounds like zeus' thundergod's wrath. It is really like lightning when a storm comes :D
