For me it Battlezone. Apparently there's still a small but dedicated group of folks who still play! I used to absolutely LOVE this game. It's a first person shooter / strategy game based on futuristic hover tanks. Some of you may remember the old Battlezone full-sized arcade game, well the PC version was an outgrowth of that game. The PC game came out in 1998, and the graphics and game play were years ahead of their time. Even today with mega-pixel monster games, the graphics are still stunning. The great part is, the guy(s) supporting it have made improvements, and you can download and play it for free! You can do either single player, or multi-player strategy or death match games. I'd love to get some more people on board to play, so come by if you're interested. Here's the link: Battlezone1.com You can find the game on the downloads page. It's a pretty quick download, and you're up and running.
