But good servers attract players from other servers too, not just people who don't play anything at the moment. You need to start it at the right moment though. Valhalla started after Tibianic and despite being a better server it had like max 50 players online while Tibianic had 250. So if I were you, Fribben, I would wait for a good moment to start my server. It would be good if you checked other popular servers to see if they get ddos, crash, loose many players etc.
your numbers aren't really accurate. when i returned to playing tibia i started at valhalla, at this time there was around 150 online everyday and about 10 max on tibianic (the players there ddos'ed valhalla all day long) this of course was in valhallas prime and before tibianic reset (where doom bringer or w/e was highesT)
that being said i understand your point
