Hmm.. from a programmer's point of view...

Generating an image from a (random?) seed? Check
Drawing circles (explosions) into an image? Check
Pixel perfect collision? Check
 -> Tweaks? Check (I could be wrong but Worms can climb just slightly (and not just stick to floor); I don't play terrain that much to have sure)

References can be used to match timings and sizes, the actual hard part though are the values. There's gravity, jump forces (3 different jumps), tweaks (i.e. the line between a bump and a crash into a wall with the ninja rope)... and there's little to nothing documented on that; though as far as I know it's possible to check some weapons through Project X, at best.
Part of the magic of W:A and what makes it so addicting, is that you can get more than a surprise during gameplay.

That is, without willing to debug or reverse-engineer the game somehow. Matching all values just right by eye? ... uh. Probably it might still not be enough, just check W:A on GameBoy, which is built from scratch and can also do everything I listed above, uses all possible references from original material (and probably including those magic numbers), yet feels completely different. The other ports are far closer because... well, they've ported the original engine (with WWP on GBA being the worst one). Also, any discrepancy in the physics can break many missions.

For comparison:

No, I'm not a noob for bringing this up.

If I host a shopper, we play shopper. If I join a shopper, I expect to play shopper. If I wanted to play supermarket, I'd join a supermarket. You get the deal.

Supermarket is NOT traditional shopper. You don't join a shopper to end up playing WxW, right? Likewise, would you stop hosting shoppers that end up being supermarkets, please? It's not rocket science damnit. If you can be arsed to setup the scheme in your HB host, then you can setup a proper title. Anything else is just lazyness or outright stupidity, don't be pajeros.

Kthx
EDIT: And don't even try with "it's CAK!!", nobody does Shopper Roper.

WormNAT2's HostingProxy is best Proxy, which works like a Proxy, and thus it hides your IP. Only the server (and the guy behind it) knows who you are.

Notice it doesn't ask "Which scheme is harder?". Notice there are only 2 options? You can either agree zar is harder or simply select no, there is no option if you think classic roper is more difficult than zar roper, there is no option if you feel they are all the same difficulty. It is a psychological trick to attempt to make one seem more important than the other.

I wouldn't want to brag about what I do and don't study or know- ...I think it's just some sort of... publicity stunt? A very basic one by the way, like openly patting oneself on the back. Reminds me a bit of the older times, UISx Clan would add a spambot for their site into #AG, and I was running xTBx at the time so I copied them, there goes a long story... Anyways, no I don't defend ads lol, but if pedantry was required, "zar roper" sounds like, well, an edited roper scheme :V
Critizing ours and theirs actions is fine (advertising has never before manipulated its public THIS MUCH, it's out of hand man), but considering earlier responses and most especially Squirminator's... I can't help but feel it's actually personal, and everyone's willing to defend this thread while pretending it's not the case, maybe pulling some advocate-level technique or something. Couldn't have worded this any better:

It's that kind of manipulative nonsense I feel I have to oppose

Meh.

-> They say Kradie is the troll
-> Komito outright does a personal attack without provocation disguised as a thread

What the hell?
