I was in about sixth grade when this came out, or at least when my dad bought it. I still love it, and it's very realistic, yet also fun to play as well! It's unbelievably fun. Games today focus too much on realistic graphics, rather than good story lines, or good gameplay. I hope to be a video game designer one day, and I wanna make games that are more like the older ones, such as this. Older video games give me a more comforting feeling than these games today that have stories that are more like real life than being fun. Half-Life (All three of them) will always be among my favorite video games ever, and even if you run out of ammo and have to start the whole game over again, so what?! It's worth it! It's worth every single penny!!!!!!!!!!!!
