I can't vouch for the later levels, but starting of War is superior. I'm in Austin, and I've played every major MMO since Ultima Online. Yes, there are trials, at igames centers you get a free 7 day trial. If you are in Austin, the birthplace of the MMO, that would mean at my store. http://tekrepublik.net/index.php/component/content/article/102-free-7-day-warhammer-online-trial-keys

If not then check the igames site for a center near you offering the trial. We have 3 people playing right now, and I'll be playing later today as well.
