DMC3 is still no.1 in my eyes. You have a big variety of devil arms and guns at your disposal + you get to fight your twin brother in an epic fight in the last mission(There are 2 other fights but the last one is my fav^^). The opening is another thing that won me over with DMC3. The twins fighting in the rain as lightning flashes and thunder rumbles. It puts me in a good mood watching the twins duke it out in the rain.(I hope they get to fight again in the rain in the future.) Rain and fighting going on at the same time makes me feel so happy.
