Yeah, the Lemmings-related strips to get a bit repetitive all in a row like that, but they're fairly humorous. I like NichtLustig in general, although of course not every strip happens to be funny to me.
A strip based on Lemmings II could be pretty fun! I remember we had one person here a while back who did some skill-based Lemming cartoons, and some of them were pretty funny, but that was a fairly long time ago.
