It's a pretty standard mir2 server tbh. Nothing really stands out, but if you've got a bout of nostalgia going on it will satisfy you enough to realise why there is no official server any more. Generic really, nothing outlandish or stupidly broken, but nothing particularly innovative either. Bugs tend to be Quality of Life issues more than anything, and any big bug gets fixed fairly quickly once the majority of the server knows about it. You have your standard, almost cliche, guilds.
Best thing going for the server are the files really, though being closed source kinda makes the server pretty hypocritical considering the foundations of private servers. GMs seem friendly enough though, but then they are likely making enough to warrant decent customer service.
TLDR: its standard mir2, if you fancy playing mir2, you can't get much better.
