I don't know anything about Meridian 59, but have been playing UO for about a
year, beta tested EQ, and am now beta testing Asheron's Call. I think all of
these games are very good and it just depends on your style of playing and what
you like. UO is more of a detail-oriented social game where you spend a lot of
time working on your specific skills, building relationships (guilds, etc.) and
acquiring possessions. EQ was more of the kill-a-bunch-of-monsters more than
skill building also with quite a bit of social interaction, but different than
UO. People criticize UO for the pk's, but as long as I've been playing I don't
find it a big problem. Yes, I've been killed a few times, but I've also walked
all over the countryside alone and am not a strong warrior type. I would prefer
UO had the pk switch, but enjoy the game immensely nonetheless. The main thing
I did not like about EQ was the interface because I like using the mouse for
movement and using the keyboard is a difficult transition for me. In fact,
Asheron's Call uses the keyboard also, but I do find their keyboard commands
easier to use and views are much easier (always had trouble in EQ when chasing
something to kill and targeting is easier in AC). I still think UO is the best,
obviously, but that's because it agrees with my style of play. Each person's
opinion will be based on what kind of game they like. I would suggest going to
each game's site for the chat boards and talking to the players, or read their
newsgroups.
