Can you describe what happens when you try to connect?

I'm having a problem after the patch. i can't play multiplayer anymore. I can connect to them via pantheon or custom game but when the computer has loaded the arena the voice says a player has left the game leaving me alone with only AI.

In custom game it says "attempt to connect has failed" or something similar.

I played online this morning "without" any problems

No router or nothing, just the network card to the broadband

Seriously? Port forwarding is often necessary, especially with bad routers and P2P netcode. There are hundreds of PC games that require port forwarding. Yes, it would be better if Demigod could better circumvent NAT so port forwarding would not be necessary, but most games that aren't running the client-server model will require router tweaks.

As much as I hate to say it, he is right in saying it is unrealistic to do so in order to play a game online, the more hoops you make your player base jump through, the larger the barrier to entry is, and the more likely it is they won't keep playing your game.  If you target audience is more casual players new to this genre that don't play a ton of PC games but think this game might be cool... the truth is those people will pick up this game.... run into issues connecting... maybe try a few times, and never play again.  Only the more dedicated players will continue playing and the community will be small at that.  Call it what you want, but if this game is trying to compete with DoTA, where only one person (the host) needs to have their ports open for 9 ppl to connect to him alone and play.... it is much easier to get online in that game... that it is in this one... because as a player I don't need to do squat to play... only to host.

Keep in mind that Impulse Phase 3 (the current version of Impulse) includes the Impulse Reactor, which supposedly has advanced NAT negotiation features. I assume that the NAT negotiation isn't quite working as intended (networking is a real pain and it's unreasonable to expect a NAT-related tool to work on all systems on day 1), so stand by and you should be able to connect without any router modification in the near future.

This game has so much potential...I love the single player mode.

I'm still not able to get into a game. I've tried skirmish, pantheon, join custom games and so forth. I have my ports opened as per the guide and I can connect some people but there's always other people that don't connect and the game never starts. Also, joining custom games usually says "failed to join".

I was able to get as far as trying to host a game w/ the arena selection panel up but no one joined my game.

It's disappointing as this seems to be a great game w/ poor launch execution.

Or maybe I'm just doing something wrong.

However, it shouldn't be so hard to play the game the way it was intended to be played.

Please help.

I seem to have gotten a grasp of this p2p thingy.

To Vow-Kyro,
I thought that port forwarding and all that actually helped but it didn't. So what I did was to find people who were in the same country/region and play with them.

Guess what. It worked.

You may want to try to play with those in the same city or town. I know it's a little strange since for most games, I can play with US/EU players just fine, just that Demigod is a bit picky on who it chooses to shake hands with.

With that in mind. Pantheon games and Skirmish games are unplayable for me at the moment because the system does not know how to differentiate where I'm from. Custom games however, work like a charm. 

Some superstitions that may be true from the testing me and several people did a couple nights ago trying to get a custom game working.

1) Failed to join game means the game room is dead.  The host left, but the server's still showing the room.  You can't join a room that no longer exists.  In fact, if you were the host, you might even see your own room in the list sometimes.

2) Failed to join game means the host created a game room with the same name as a room that was 1).  Change the names of your room.

3) The more people joining at once, the more likely nobody can join the room, because everyone has to make connections with everyone for you to enter the lobby.  If you're on vent or in-game chat, it's best to have one person join after the other instead of all at the same time.  Not as much of a problem with the kicking mechanism.

4) Check your ports.  Ok you forwarded your ports, but use a tool and check it really is open, there are several around the forum.  You may not be doing it right or there may be something else going on.

5) Even with open ports, if you have a crappy connection, e.g. someone's file-sharing on your connection, you may still not be able to join.

Well, to put things in perspective, back when I was at university, most Valve games did not work. Valve's response was, "Too bad."

At least Stardock is putting forward an honest effort to get things working for players, regardless of router configuration.

That's not my point. Stardock isn't saying "well it's not our fault," which is the response other companies would give. My point is that Stardock is doing its best to make things work in all sorts of environments.

in some cases it helps, if your router is up2date and has a new firmware.

try this one.
