Hi, Chick!
I haven't played Phantasmat yet, but I did buy Lost Lands and thoroughly enjoyed it. It was also a good length, compared to some of the new releases.
I'd suggest you download the demos for both games to see which one you like the best. Of course, today's new release for Club members looks interesting so, if you pick that one up as well, you won't have to make a choice
