StingingVelvet: And this game has that same secret hunting. A lot of the rooms or areas are also equally large. Just not quite as large on average.
Obviously Call of Duty is ten times more linear and railroaded, but the idea of the original Shadow Warrior being a lot more nonlinear and large than the new Shadow Warrior is nostalgia goggles, IMO. I just played the original recently.
Secrete hunting isn't necessarily what I mean with regards to level design, as my post revolves around your idea that the design is just "key -> door -> next area" in terms of linearity. This isn't true, for the reasons I stated above.
Saying "While some of the rooms might be a little larger I doubt it's overall very different." is like saying Super Mario 3D Land levels aren't much different than levels from Super Mario 64. It's just not the same. If I want a Coke, give me a Coke. Don't give me Pepsi with a Coke label slapped on it and tell me it's "basically the same" because it's not. This game is Painkiller with a Shadow Warrior label slapped on it.
That's not to say I think the new Shadow Warrior is bad. Painkiller-style games are a whole lot of fun to me. The problem is that Painkiller-style games haven't stopped coming out, while games like Doom, Duke Nukem 3D, Blood and the original Shadow Warrior have. Having a game come out named "Shadow Warrior" is semi-misleading and makes fans wish the new game was modeled after the original game rather than another game entirely.
Lastly, I didn't play Shadow Warrior
until recently. It's definitely not nostalgia goggles for me. I like the new game, but I can 100% see where people are coming from here.
