Very true, the excessively maze-like and/or puzzle-oriented level design is probably Shadow Warrior's weakest aspects. Once you get past that though the game is pretty damn good.

SW2013 on other other hand went the complete opposite direction with relatively linear level design with arena elements. IMO this severely damages the replay value.

If I was making SW2013, I'd take the current game, change the level design so that it's a bit more mazelike/explorable and folds in on itself more, and I'd make the weapons more powerful/functional. Then the game would be pretty solid.
