So yeah, one day I decided to stop being so damn scared when it came to playing games like Doom and Quake, and started up my DOSbox, and I decided. I'm addicted. I love Doom, Quake, Duke Nukem, Wolfenstien, all those old DOS games. Just a few hours ago I started using Zdoom to play my Doom games, which makes it alot easier, considering how you can mouse aim more fluently than Doom on the DOS. I hope there's mods for Duke Nukem and Quake to make mouse aiming easier. I just have a hard time using my keyboard to aim.
