Hi EliasFYes of course.
The main point of this network is - that You can easily create your own server on your PC and invite friends there. So your argentinian ping will match others there and everything will be fine and smooth :) Others from Europe can join your server also but they will have ping and time zone issue obviously (5 hours difference) as you know ;)
Just in case you couldn't find it on this website in HELP section
- here's direct link to the basic tutorial about hosting your server, unchanged since begining of the network 5 years ago: https://crymp.net/faq_own_ssm_server.phpGood luck and have fun with friends.
