Half-Life 2 is simply amazing. The source engine makes it one of the best looking and most realistic games yet. It takes a powerful gaming machine to play though, but it's worth the upgrade. I was running it on my Geforce4 4600TI and it looked great, but I knew it could be better. So I upgraded to a Geforce 6800 (mainly because of HL2) and got the results I wanted. It did effects better and using the latest Direct X it was able to do graphics better then before. This one's so real it's scary. Just wish I had a gravity gun in real life, i'd love to launch stuff! I wonder how many mountain dews I could launch at lightning speed, probably more than those commercials. :) Oh the possiblities...
