I'm currently playing World of Warcraft and can fully suggest playing that, because it is very easy to get into.
Perhaps a little to easy for my likeing in the long run, but I'm sure I'll have at least 5-6 months of fun with it when it goes retail in Europe.
So that is a suggestion if people are interested in MMORPGs and want to start up in one. I'd still not advice playing DAoC from new anymore, as mentioned ealier.
I think next week I'll give Wish a try before the beta ends instead of WOW, because that game shows to hold a lot of promise and much more debth then WoW in the long run, but I can't really comment that much on it - amongst other things because I've not played it much yet

and - naturally - the NDA.

EDIT: or rather - I'll not, because I just noticed (danged, learn to read Xandax) that Wish has been cancelled .... damit.
