It's not just the level design, but the lack of checkpoints that bugs me. Honestly I think I've only beaten Duke 3D on the XBLA version and N64 co-op, since those at least allow you to respawn in the middle of the level. For that reason I could never really get into Doom, but I'm not sure if there are versions out there with more forgiving respawns. Health is another thing that annoys me - I don't love regen mechanics (especially when the cover is too abundant), but being stuck at low health on a level mostly cleared of enemies sucks.

Half-Life 2 (and maybe the first Half-Life is like this, but I haven't played it) is the only FPS I've played that really nails the structure. You have health, but it seems to do a good job of dynamically giving you what you need and there are plenty of recharge stations. There are checkpoints, but the game is basically one continuous level, so it's understandable and not overly generous. The overall structure is linear, but there are little puzzles all over the place that don't involve esoteric keys and mashing the action button.
