The thing is pkers make up a large proportion of the game and people like a game that you can be competitive about. They want to win. In killing people with great equipment they've won and your the loser because of a number of things. But thats just typical mentality of people. For them the taking part is never enough they want something shiney to show for it as well. Most likely the ones that when they run a race and get less than third place throw a paddy about it.
To me rpers need to be more mature in their thinking about a game, it not only takes a great deal of commitment but imagination, being sympathetic towards other's feelings and want to be involved but let others be involved too.
I don't think any game can hope to attract enough of these types of people because its a mindset thats needed to create them. People generally want to pick up a game have fun, feel they've accomplished something by getting the shiney thing and put it back down again till they pick it up again to get an even bigger shiney thing.
I've recently logged into KR again, and thankfully now it can fit to a windowed screen properly but i found it still made my eyes hurt because of the graphics. Yes things are looking more tidy now. The deco in my house doesn't look like a pile of crap piled together it looks like it should do, including my bed that at first looked like a heap of cloth, with the polar bear rug hovering on top. So they are making progress with it, just like when UO was young and new it has things that need to be ironed out and its getting there.
Personally I don't feel there's enough advertisement outside of the USA to draw in new players. I mean WoW was even played on South Park, how big an advertising endorcement can you get? No longer is UO on the shelves in stores in the UK, but games like WoW, Acherons Call, Guildwars, LOTRO and Archlord are. People generally walk into a shop to pick up their new game. To find UO you need to either stumble across the website or maybe a small advertisement on a website showing other games that look alot better.
I hope UO does continue to have a long life, although I'm slowly playing it less and less because of RL which may eventually take over the need to play a game. Though UO has been more of a social thing to me as my friends have grown up and moved away or gotten lives of their own. Or maybe as I've become more of a hermit and happier to talk to people at arms length.
