>>715645273 (OP)I've replayed it in full over a dozen times since I was a kid. The responsive movement and fast-paced hitscan gameplay is addicting and fun, but it's got some problems, notably the weapon variety and especially the level design. There's softlock issues in Episode 4 that can ruin a playthrough. The first two levels of Episode 6 are completely tedious trash as well, but the last half of the same episode has the most intense and engaging levels in the base game, especially floor 6 where everyone in the level gets woken up and there's not a single safe spot where you can just camp and bottleneck enemies, forcing you to stay on the move. That's Wolfenstein 3D at its peak. Most of the time, though, you're just trundling through square rooms and hallways that don't offer much in the way of challenge or strategy depth.
One really good thing about Wolfenstein that is understated is the excellent sound design. Unique callouts, loud door opening sounds with directional audio, and enemy shots sounding accurate based on distance. I also love the simple AI of boss enemies and the Fake Hitlers that don't just go full aggro toward you like the standard grunt enemies. They strafe around, flank, and retreat when not shooting. If you play any mods, you'll likely see this more often with more standard enemies, such as the flamethrower guys in Castle Wasserstein. It shows that a modicum of thought was put into enemy AI in FPS games since the beginning. Finally, the game is just cool, action-packed, and does still provide a decent challenge in some moments due to the lack of armor and punishing nature of the enemies themselves. However, it's still ultimately a fair fight because non-boss enemies are hitstun when hit, and you can move at light speed to break line of sight the moment you know you're overwhelmed. It's stressful, but that's part of the unique charm. It's not a power fantasy at first, it's a gritty fight for survival, but it can be a power fantasy once mastered.
