Do you remember when we had 500+ Old graphics? 150 MAX. now. with new. so old graphics is better x100 time.
A playercount is not solely dependant on graphics. Moreso on the content of the game, how long it has been running and if there have been issues that cause players to quit.
Considering the duel arena is broken at the moment it's logical our playercount has dropped. With the duping issue back in febuary before that and a pretty large amount of ddoses somewhat recently I'm not suprised at our playercount.
It's also logical that we haven't ever passed 500 players since emps world simply hasn't been up as long as emps world. Private servers have lost players in general due to OSRS, this is something that affects all private servers. Even ones with the same graphics as old emps.
Graphics are nearly the most irrelevant thing to a server's playercount. Plenty of people like old graphics, plenty of people like newer graphics. Servers keep players based on content, no matter how good a game looks you wouldn't play it if there was nothing to do. I don't know why that's so hard to understand.
