While I was fiddling with multiplayer for VCs 4 I was starting to believe that multiplayer with more than two players wouldn't be as difficult as Joseph thought before. It would be still much work, but not impossible at all. I don't know if it's worth implementing because I don't know how many people would really use it, so I started this poll to get some info.

Before voting, consider the following things:

• - It will be Windows only. DirectPlay allows some features that makes it easier, and I don't want to reproduce these functions under plain DOS.
  - The bandwith needed will increase with every new player. With two players, two machines need to send packets to the other, this means 2*1=2 packets at a time. Three machines would send packets to the other two, this is 3*2=6 packets at a time, 4 machines send 4*3=12 packets at a time etc. up to 8*7=56 packets with 8 human players. I don't know how many bytes is that, but it may require fast LAN with many players.
  - If any TTD freezes or disconnects, every other machine will freeze (or fall back to single player if you've enabled it). Desynchronizations will be harder to solve, either (you'll have to copy one savegame to all the others and use sv2flip on them. The current version can't do that of course, but I'll update it if I finish this feature)

Now that you've read this, please vote. If there are enough people interested, I'll really start working on this.

First I want all other stuff working in multiplayer safe without desync,
then I couldn't play it with more than two people and it would make multiplayer aware patches even more complicate :/

Maybe I have time to test TTD Multiplayer in a few seconds...

-edit-
And I think the impossible screen res change I would like more

I'm unlikely to ever play multi...
Even then it would only be against one person.

Is it worth it ?
Some jokers will say yes, but at the end never play
Don't do it !

I'd like to play stable TTD someday .... if it would be stable (and I have some time) then I ceertainly would play (maybe over Internet to)

Ok, played a little bit multiplayer with massive savegame usage, nice (With AI Player )

Ohh, and dynamit is somehow unstable even patched, lets look if we find a solution...

I second this oppinion. No sense making an unstable 2+ player multiplayer if we always get desynch problems.

is there currently any way to play ANY stable TTD multiplayer game running XP?

it is getting stable, check newest TTDPatch experimental versions

I think I dont understand it overall - it will be this multiplayer working via internet or LAN (or both)?

I do belive it does nothing but making TTD not quit... No CTRL processing tho, i belive.

- signal type selection (with extpresignals on)
- buying additional train engines and changing the direction they're facing (with multihead on)
- borrowing and repaying the maximum amount (with debtmax on)
- removal of industries, transmitters, lighthouses etc. (with the appropriate bits of morebuildoptions on).

And then Csaboka added the rest of the stability features.

Witch means stable multi in some time?

Would try it if I could do it via IP

Silly person, all multiplayer in TTD win goes by IP...

Really? So where do I put the IP number in eh? I do see it... all I see is modem IPX and TCP. Not IP.

@ BobXP (gmyx posted just before me)

Not necessarily. Ever heard of IPX/SPX? Or a serial cable? Those don't use TCP/IP or anything/IP.

select TCP and it will ask you for ip

Assuming it can be made to work by IP address over the Internet AND through firewalls, then this would be a great thing. This is because it is lots easier to get 3 or more people to play the game throughout the entire Internet, than in one physical place at a time. I'd play it with my brother and wife, on my internal network and over the Internet combined.

BUT it's not worth doing until all the Patch features work in multiplayer without crashing - the Ctrl problem solved, for instance. I haven't attempted multiplayer in years now, so I don't know how much better it's gotten.

There may be some other issues - such as, do all the computers automatically use the Patch settings of the host system? Otherwise, either there would be playability problems, or the big coordination pain of manually making sure all the CFG files are exactly the same.

I doubt I would ever have the length of time to play multi-player against one person, let alone more than one. I think that you should only work on it, if you want to see it done, and you would be able to use it .

I appreciate what you have done so far, only do this if you see a use for yourself.
