It is true that few strategy games support rejoining, probably because their matches are intended to be far shorter than the average Sins match.

Regardless, it is simply a programming challenge which needs to be solved. The only issue is that an AI takes over a player's forces once they disconnect; the developers would need to formulate a way to relinquish force control to the player once they rejoin. Seeing as force control can be relinquished to an AI, and multiplayer matches can be saved, exited, and resumed at a later point some of the code structure is already nested in the program. It simply takes effort, and it's a feature which is vital to the gameplay experience of most players whom at some point disconnect.

I cannot fathom how there could be any Sins player who has not at some point in their multiplayer experience hoped for the ability to rejoin an ongoing match if they have just crashed.

The reconnecting player need only know the current position and status of all objects in the game, which the host can transmit. There is no need for the reconnecting player to know every action which has taken place while it has been gone. The match would simply need to pause while the disconnected player reconnects, and then resume once all data has been transferred to that player from the host.

I didn't elaborate myself clearly enough I see. The pause would take place once the player has initiated a reconnection, giving time for the host to transfer relevant game world data to the reconnecting player. Once the transfer of data was complete the reconnecting player would be "in-sync" with the rest of the players, and the game would be able to unpause. The game needs to pause while the player is reconnecting in order to prevent a desync due to new data appearing but not being transferred to the reconnecting player.

An AI would still take over the disconnected player's forces as they do now while and until the disconnected player chooses to reconnect. The pause would act like lag pauses do in games like Company of Heroes where the game will pause in order to ensure that the lagging player does not become desynced.

I'm not too learned in net code, but isn't it possible once a connection is lost all players would do an autosave and they could just rehost from that point? I made no intention to over simplify it, but the point is made.

Unfortunately after-crash savegames tend to be borked, I'm not sure if autsaving upon disconnect would work for the crashed player.

If you could choose the autosave-timer manually and set it to something like every 5 minutes (it's 15 right now if I remember correctly) there should be no issue in people restarting the game at the last autosave... We do that all the time, i.e. if our provider executes our 24h reconnect at the worst time possible. My rig could probably handle autosaving every minute, too, so it'd be a huge advantage if I could choose a shorter interval.

Even if we play using Hamachi it shouldn't be too different with ICO, it should be enough if one of the players has a non-broken pre-crash savegame.

How would the disconnected player receive the autosave?

Its not about reloading from a save, its about loading into a live game.

What is being suggested is possible, as far my coding experience tells me, but it would be difficult to, relinquishing control to an AI and back wouldn't be too hard, you can do that in Single player by quitting and reloading a game as another person. My problem with this would be, a player D/Cs (disconnects) on purpose and lets the AI 'fix' his stuff, getting upgrades, research, etc, that he didn't think about.

The fact that AI takes control in Sins makes it WAY easier than say in, Warcraft where your allies get the split of your stuff.

As far as making a autosave and reloading it once the disconnected player returns, this doesn't work because if the disconnected returns much later, causing a large amount of time to be undone, players would deem it as unfair.

Uploading information from the 'host' to the D/Ced and R/Ced player would be possible, but depending on the map size, how late in the game it is, how many ships, etc, could take awhile, but would be well worth it to reconnect.

As far as my suggestion goes, what if you could host a savegame as a map? Kinda like in Warcraft 3, everyone has to download the map from the host, why can't a save be used as a map with all relevant and important information in it? Ex, player credit, metal, and crystal amounts, researches, ships and positions, etc.

Cheers.

I think it's a fundamental error for Ironclad Games to have, as it seems right now, completely ignored the need for the ability to rejoin hosted matches which people crash or lose connection from.

When you are playing with friends and one of those friends leaves the game unwillingly, there is no moral left to continue without that friend. Players should not have to deal with that issue, as it is putting some players off playing PvP matches full stop.
