I wanna pa game using this!

Went to my cousin house the other day and saw this 6 years old kid playing warcraft III using this 39" TV...mother fooker... he cant even beat the easy AI 2 on 2 using cheat! It's a bloody luxurious waste for him! Hmm but on 2nd thought, if we were to play CS or dota using this TV, would the navigation and controlling be more difficult?
