I was thinking today... why not rename the remake maps (such as field, islands, walls, ect)
Something simple and distinctive but not unoriginal.
I suggest renaming them because they are remade versions of old concepts, not the old concept itself. Look at the Halo series, for example. In Halo 1, there was a multiplayer map called "Blood Gultch." That map made a reappearance in Halo 2 as "Coagulation." In Halo 2, there was a map called "Lockout." In Halo 3 the remade version is called "Blackout." The new versions were almost exactly the same as the old versions.. just with some added graphics and visual aesthetics.
New names give the maps a new flare, and believe it or not, add to the nostalgia effect.
