I just tried Shadow Warrior and I liked the gameplay. It's much smoother than Rise of the Triad, in my opinion, and a bit harder, which is also a plus. I died a few times at the start until I figured out the layout of the first level and how the weapons work. I really like how enemies fall into pieces after you slice them and the blood on your hands after engaging in melee. Cool game.
Oh, and for all of you who purchased the game off of GOG, I just wanted you to know most of those Apogee games were freeware. You just paid for the compatibility, which could be done in Windows 7 and DOSBox with a half hour of your own time. Check the official 3D Realms website for free versions of ROTT, Shadow Warrior, Duke Nukems, and more:
