PimPamPet: Besides, they can't be as bad as Noah's Ark 3D... I mean, at least they give you guns.
I very strongly disagree. I think Noah is better than Wolfenstein. It has two projectile weapons, two powerups (map and backpack) and a built-in minimap. And it doesn't overstay it's welcome, like the nocturnal episodes of Wolfenstein do.
The lost missions are really bad. They feature the worst level design of all more or less official Wolfenstein engine games. They have lots of required secret rooms, that are not easy to find.
Noah has one of those as well, but the minimap combined with the layout of the level reveal the position of the pushwall.
Edit: Oh, and Noah as an excellent difficulty curve.
