Experiences in MP gaming
Well, I've to say it: the only reason for what I've not abandoned EU MP gaming is because it's a heck of a good game

. Any other game with such a great number of crashes in MP sessions would have a very short life in my hard disk.
I've been playing on a regular basis (almost every night) many campaigns (mostly IGC) with an average number of 4 to 5 players, with a varied range of speed connections: from modem 56k to DSL 256 kb/sec.
Well, you guessed it: lot of crashes...but fortunately this game is so involving that we keep reloading and restoring again and again...
The tech requirements to play MP, as stated in the game box, is not only a somewhat cynical sentence (512 kb/sec! it's like saying "...to play this awesome 1st person shooter with all graphical options you need a Silicon Graphics Station..."), but it can be wrong.
One of the regular players has a 56k modem. We're playing a 5 players campaign, and this dude had NEVER a crash. This has brought me to think that the speed of the connection is not the most important aspect, but the RELIABILITY of the connection.
I'm not a tech wizard, so I haven't any idea about what this means, but I think it's curious enough to see cable and ADSL connections ranging from 128 to 256 kb/sec causing some crash now and then, while a simple 56k modem has never lost connection (or been dropped to the desktop) in any of our long game sessions.
Hope this may be of some help in the search of solutions to the MP unstability of EU gaming.
