alexx honey.. i'm on the closed beta as well and have played for a couple of minutes today and yesterday..
there are some screens and videos on youtube/esro forums.
i didn't believe it myself, but they have really done a nice job!!!
and no.. it's not a sea or sremu emulator ;)
believe me or not (i never lied to anyone), esro is real, the server is in progress, and there is stuff being added day after day...
there are just some minor bugs that appear that have to be fixed to ensure server stability.and that costs developing time ;)
--edit--
1st:look for ESRO at youtube. you may find some closed beta videos ;)
2nd:i'm sure you can trust me if i say that ESRO is real,and they are in beta stage!!
nah..not beta stage like in other fake servers, but beta stages where new stuff is being tested by chosen 50 people. the beta will only be over after the project is done.
so no pre-release or whatever ;)
