Usually I try to beat or get very close to beating (in the case of racing games IE burnout) before doing some kind of reflection. So for counter strike since I couldn't really "beat" the game, I decided to play close to 10 hours before I put in my 2 cents. Now I suppose the main reason I switched to source is because I tried getting into 1.6, but found myself getting my ass handed to me every time. The aiming is to difficult to get used to when you're against people who have been playing since it came out. So when I tried source at a friends house and relised that I could actually do well and enjoy my counterstrike experience I decided to give it a shot. The first thing I noticed is the obvious fact that it is indeed easier than 1.6. Sprays are more accurate, and the bullet pattern isn't as wild and hard to get used to as 1.6. Thus a simple little concentric circle movement of the mouse whilst shooting the M4 or AK can mean a lot more than it used to. Also the fact that you don't have to buy ammunition is a plus .Another obvious plus would be the improved graphics. The graphics have improved 10 folds over 1.6, without you needing a power house computer. Source requires 265mb of ram and I think a minimum 1.2 GHz processor. Along with customizable sprays and better mic support there's really no downside to counter strike source. The only con I could think of is its less 1337(leet). Now I'm not the gamer whose uses such words as leet, and PAJOWNED, but there are people out there like that. With the harder aiming point in 1.6 people claim it takes more skill to become good and play in CAL leagues. Well frankly, there right. As I said before I was getting my ass kicked in 1.6, but source just felt right. Oh well, think what you will, but I must say Counter Strike Source provides for unprecedented FPS experience on the PC.
