"Be very carefull before you join!"
Simple to play (old client), no installing necessary
For somebody (especially children) could be habit-forming. Ambiguous or faulty rules (you'll find later when playing). Rude administrators (especially CZ/SK). Often swear words and abuse in chat used (seen in CZ/SK). Instability/errors in GUI.
My experience with DO (by German BigPoint) is very bad.
Administrator can ban you from chat or user forum for more days without any warning or noticing just because of two letters in name e.g. (in my case BA= Bratislava) or for copying one Wikipedia page at user forum (30day ban) when arguing about that "BIG" should be added to The Rules, so users can recognize, it's a "crucial personal information", they cannot mention in chat (or 7days ban).
Administrators (CZ/SK) use sweard words in replies to users i.e. "an*l alpinism" or "as*-crawler", etc. If user asks to get any explanation of The Rules, admins sooner or later ignore him or block him on user's forum.
In chat (even in "prime-time" 8:00-11:00PM) is often a rude language, abuse and insulting seen. Children can join this "trash talk" without any problems.
Ambiguous or faulty rules are hard to find from the main screen (but you'll find game features easily). There're no list of penalties mentioned in The Rules, so it's a pure administrator's "free-style").
So if you're calm, asking nothing just paying for Uridium, everything is ok. But if you are at the top with ship equipment (no much further fees expected) or mention any technical problems with your ship in chat, troublesl begin (jeer, ban, blocking, ignoring...). So my advice is, be very carefull, if your consider to start with Dark Orbit!!!
