I play mostly on off-hours, and while it can be pretty empty I don't mind that as much (and neither does my computer...hoo boy). There are tons of people on during the weekends however.
The community is pretty nice, many new people and many end-raiders. You shouldn't have much trouble finding a static if that's what you want. I see lots of smaller FCs recruiting too, so that shouldn't be too much of a problem.

Lich is mostly English speaking; probably the second biggest language I see is German.

The marketboard isn't super vastly inflated, either, at least from what I've seen of other servers and compared. There is maybe, three or four housing plots (mostly M and L) left in each ward last time I checked, so if you're interested in that....better find an FC with a house.
