I will answer FoxHound first since his is shorter:
Fly Shopper uses exactly the same Shopper scheme. Surf Shopper requires some TestStuff features, so the scheme is a bit different.
Yes, however before 3.8 weren't those commands you entered in the game lobby or needed wormkit for? Like they were not actually part of the scheme settings in the base game? So I didn't count that as being different because they still use the same scheme file? It has been a few years since I played Surf Shopper so I forget.
Like how with Darts and TTRR/Big RR etc we would type !rs or /rs for racingstuff.
the scheme options are the same, and they are shopper variations indeed, but they are completely different from simple shopper. and for that, they could be added in my opinion
Completely different? No, they share more similarities than how much they differ from each other, they are different in 3 ways:
Surf Shopper:
1. Depending on the design, the map design is generally open at the bottom, in which you need to hide appropriately away from danger as best as you can.
2. You need to learn how to skim your worm, though it's a simple technique a good roper should be able to learn within 1 game.
3. 1 Extra Rule - Surf before attack.
Fly Shopper:
1. Depending on the design, the map design is generally open at the top in which you need to hide appropriately away from danger as best as you can.
2. You need to learn how to throw your worm and judge distances though this is also a simple technique a good roper should also be able to learn within 1 game.
3. 1 Extra Rule - Fly before attack.
Both schemes have the exact same core gameplay and purpose, collect a crate and attack worms, hide as good as possible, use the weapon you collect as best as possible, and all variations of shopper maps have dangers due to open spaces and different types of hide.
Even with these 3 differences, other than learning 1 extra manoeuvre in each map variation, 2 in total for the 2 schemes we are discussing, generally speaking with all maps the roping is pretty much the same where you have lots of time to get around.
For a newbie, the 2 extra manoeuvres will present a risk to them which they will likely fail a lot, though to any skilled roper it's no more difficult than any other basic manoeuvre like spikes, shadows, outlaw, dragon, etc.
because when you are playing surf or fly shopper, you are not playing a shopper
Do you not realize all variations of Shopper maps are direct descendants and sub-genres of Shopper? Therefor they are still Shopper.
Notice they are called "Surf Shopper", and "Fly Shopper", and not just "Surf" or "Fly".
So yes, you are actually playing a Shopper, because it's the Shopper scheme you are using.
The point is, you can literally use those maps and play Shopper because those schemes use the "Shopper" scheme, and the "Shopper" scheme is technically part of the Allround league.
Surf Shopper and Fly Shopper are slightly more challenging than normal Shopper, though they use the same scheme.
The same can be said for WXW when using maps with W2W/W3W/W4W/W5W/W6W/etc which increase in complexity, and therefor skill.
The same can be said for TTRR maps and the difference in width/height between walls and floor to ceiling, though we don't call them "Tight TTRR" and "Wide TTRR"
The same can be said for Intermediate using Open Island maps and Cavern maps, though we don't call them "Open Intermediate" and "Cavern Intermediate".
The same can be said for Roper when using more complex maps increasing difficulty, though we don't call them "Complex Roper" and "Simple Roper".
The same can be said for Golf where different types of shots and angles are needed, though we don't call them "Advanced Trickshot Golf" and "Simple Direct Shot Golf"
The only real reason they added the technique into the map name, at least it's my belief, is for the longest time Shopper has been known as being an entry level scheme, so noobs can tell the difference of the maps and easily know they must follow the extra rule.
I am on your side here, why are you trying to make things complicated and argue with me when I am supporting you?
They all use the same scheme, yet different maps.
Edit - Oops, I somehow soprano'd a sentence so had to go back and finish it lol.
