what do you like about this game?

The fact that it's online, so it's completely random who you'll run into at any time, also the size of the world and variation of things to do, mean that it has staying power, and if you get bored of playing the same character you can always make another completely different one, and explore a side of the game that you've played less - fighting, crafting, hunting, and even decorating are all possible in this virtual world.

I like any scene beautiful, interesting plot of the game.

yes, meet some very interesting people on it also

Well, it was originally my very first MMORPG that I started playing (can't count Runescape). The thing that attracted me most, and what I miss most in other games, like WoW, is the lack of possibility to play without fighting, e.g in UO you can just be a miner/blacksmith, etc, and never really have to fight (EVE online come close I think). You could always hire guards against those nasty PK, and pay them in products or something. The freedom of action was really the best. I loved stealing from other players and such. I still play it from time to time, even though I have switched to WoW:TBC.
