A few years from now there're gonna be posts in these forums about how Halo (7, 8, maybe 9) just don't have classic Halo maps like 4, 5, & 6 used to. Where's the new Plaza? Where's the new Riptide? Where's the new Torque? That's what they'll say. Mark my words. Because honestly, half those "classic" maps you named play like garbage unless maybe you're at the pro level, and none of them are much of anything to look at compared to almost any map in Halo 5. This whole thing sounds like nostalgia to me.
I disagree, as we have already seen the only maps that people ask to see return from 4 are haven and exile...aka the 2 maps that made up half of the rotation in H4.
In my eyes plaza and mercy are the only maps that break the mould and even then Plaza has a bad green filter on and some copy/paste human themed geometry.
It doesn't even have to play well to be visually distinct, gemini from H2 is a bad map, it has a weak layout and unintersting gameplay, i would argue that it stands out visually more than H4 or 5 maps. All the human maps in H5 look like a glorified forge canvas, mainly because of how paint by numbers all those maps look.
To just use some 4v4 maps, lets gather 8 maps (the majority) from each game.
CE: Chill out, Hang em, Damnation, Ratrace, Derelict, Battle creek, Prisoner, Chiron
Due to the age look a tad samey texture wise, even then still some diversity.
2: Beaver creek, Warlock, Sanctuary, Midship, Lockout, Elongation, Ivory tower, ascension
I dont think you could visually confuse any of these maps, they all look distinct from each other.
3: The Pit, Guardian, Construct, Heretic, Narrows, Snowbound, Isolation, Orbital
H3 reused the forerunner theme a bit with Construct, Epitaph, Cold storage and Citadel, but otherwise the map pool seems diverse.
Reach: Zealot, Countdown, Reflection, Boardwalk, Swordbase, Penance, Powerhouse, Battle canyon
If it wasn't for CE:A then anchor 9 and condemned would of been the other 2 maps, and would of been all the 4v4 maps available. The closest you get to similarity is Penance and Zealot being covenant themed.
4: Haven, Skyline, Abandon, Landfall, Adrift, Solace, Pitfall, Monolith
These are all the proper 4v4 maps, the rest are mid-sized like complex or vertigo, or big. All maps can be categorized as human or forerunner and they share many visual themes, to the point they feel less distinct. Haven, Solace and Monolith all look different but their landmarks look samey. Skyline, Abandon, Landfall, Pitfall & Adrift have a different theme but many of the same pieces and textures.
5: Plaza, Rig, Coliseum, Empire, Fathom, Torque, Truth, mercy
Riptide, Eden, Regret, stasis, overgrowth, molten are all remakes, i'd argue tyrant is a soft remake of Coliseum, that leaves the Haven reskin as the only map without a clone, that immediately makes them all less interesting. Plaza, Rig, Empire, Fathom, Torque, Riptide, Eden, Stasis, Overgrowth and Molten are all human maps and they all share very similar geometry or even just geometric style making them look more homogenous..10 maps.
Why can't 343 design a human theme and have 2 maps within that theme not look really samey, it's as bad as the H3 example of Construct et al that i gave..except in H5 they make up a majority of the 4v4 maps.
