XKCD is going a bit low on inspiration IMO, I hope he finds back his creative spark soon I am still very hopeful, however here are two other comics I think deserve a measure of attention.
http://www.blastwavecomic.com/ , I tought some people could find proper interest in this one, as PBEMS are more often than not dens of good ol' geekdom. This comic is all about infrantry kind-of wargames clichés and is quite sharply done even tho the updates are very erratic(several months sometimes between updates). I think the artist is a game concept artist and is swedish or norvegian (at least I am pretty sure he is a descendant of a big hairy viking country other than finnish or icelandish) and the art is all computer pencil.
second one is
http://www.sinfest.net/ , a possibly offending comic for
very sensible christians. Christianity-themed sarcasm cartoon done in old-fashion panel style by profesionnal cartoonist. The dude is often keen on his insights even tho I think he has been going slow since a couple of months but if you check the archives they are often worth it. (took me two weekend to go through it when I found it, but couldn't stop).
just a sidenote. english is not a native language and its especially obvious when I am tired, even tho I will come try and often re-edit my posts to avoid sounding too foreign.
