hmmm, most people have different understandings of small / medium / large, like my wife for example
When you say that original Quake maps are small
, then I like the medium
ones the most. Like it already has been mentioned, large maps can tend to make you lose orientation/focus/goals.
Of course, there are always the map-types that lead you like a tunnel from beginning to end. These kind of maps (where you do not have to re-visit areas a couple of times) can be as large as possible, because you cannot get lost.
But the ones that needs to re-visit several places, need some orientation marks.
Just like maps from sock and others have ! They add signs and stuff into it to make it clearer.
Quake (speaking from original game idea) is a faced paced shooter game with narrow passages and linear playthrough most of the time.
Expending this idea (and make it open-world like) has some risks and to avoid that you need a smart traveling system while mapping (some signs or hints or a cinematic clip when pushing a button that shows you what just happened and where).
Looking forward to see your maps
PS: I was talking about Single player of course. Multiplayer maps are always cube like.
