I discovered the series a long time ago in an unlikely way: A mod called Beyond the Red Line (now discontinued) had three action packed BSG levels I played quite a bit. A few months later, I found The Babylon Project, and soon discovered that the two mods were based on the same engine. I looked into the game and finally on August 28, 2009, I gave in.
Now, at that point, I was a rather good player, but I had developed a knack for finishing whole campaigns in one sitting. Having a good joystick at my side, and a level head in combat, I dove into the first game. Truly amazing stuff. Sure, the resolution was low (640 x 480) but it was still a blast to play. I moved on to Freespace 2, before I decided to get FS Open, and play the games AGAIN with updated graphics. I don't think I've found a game I play more frequently than this. The only drawback is that the multiplayer service is rarely, if ever used. I have yet to play a single online game, but the concept intrigues me. Buy. This. Game. With FS_Open, the replay value is almost limitless with great mods like Blue Planet, FSPort, Just Another Day, and others. PLAY THE FREAKING GAME! DOO IIIT!
