You do realize that there were many releases of Wolfeinstein and already a large search database on Wolfeinstein. Also, I am not interested in aimlessly looking for websites to back up YOUR claim. Also, to tell me to search something is just lazyiness on your part. Otherwise, you really are just pulling stuff out of your ass. I did two searches suggested by your verb "Google" to go to google.com and look for it myself. By searching "Wolfeinstein", I came to one where it was the original Wolfeinstein game, Wolfeinstein 3D.
My second search I typed in was "Wolfenstein, Doom 3 engine", which resulted in basically a bunch of forum posts.
There is only so much the binary search method can do for its user. Also, if you don't know what the binary search method is, how about you google it.
As for the Sci-fi, it is in the game. It even part of the game play.
How about we just remove the weapons, ammo, and life system and we would get Myst. I guess that makes every person shooter a clone of Myst with guns. Besides, unlike the generic first person ww2 shooter, there is an amulet that manipulates gravity and all sorts of shit.
Again, as for the hands on experience, bring out a website. It doesn't even matter for the most part. We are talking about id Software. It doesn't matter what the previews are like. What matters is the final copy.
