Oedi: indeed there were lots of desync problems with the original release, but the gold version fixed almost everything. i still play the game (Physical Gold v1.60) a lot with a friend over hamachi and we haven't encoutered any problems. only once, when we tried do play a game with 16 bots, i guess the game couldn't handle that, it got out of sync in like 5min. anyway, the game should be stable, though i can't say anything about the GoG release since i haven't tried it yet.
Mariws: Hello!
Could you spare 5 minutes to explain to me how to make Srttelrs 3 work over hamachi. I have used hamachi before with other games but I can't make it to work with settlers. My friend can't see the games I'm creating.
Thanks in advance!
im so sorry, i recently switched all my computers to arch linux, so i cannot help you directly, but i might be able to help in another way.
most important for playing over hamachi is opening the ports the game uses, it never worked for us with closed ports.
