for now there isnt any alternetive unforthently.
No one will probably bring back a game from 2013 but never stop hoping maybe one day someone with a brain will make a fine dbo server in the next year. Or we can wait for dbog 2.0, winter 2018 is in just a few more years.
If someone even decide to bring it, it needs to put aside his emo and stubborn nature and build trustworthy team, where main focus will be to balance game in PVP and PVE for real this time and bring it up to modern MMO standards with better events and other systems.
DBOG Clone, won't do any good.
