Having been the sole programmer carrying the title "Senior Web Developer" as if there were actually any other developers on the team, I appreciate the irony of a one-man art team...
On the other hand, we can't actually hold Grimm Omen responsible in any way, shape, or form for any of the artwork that appears in Ultima Online because projects he claims to have been working on have never seen the light of day, he certainly takes no responsibility for the bad artwork in the game, and we've not seem him admit to having completed anything that would remotely be considered good. He can't even decide whether or not he was part of the group or process that green-lit or did not green light, inspected or didn't inspect, or in any other way did or did not have anything to do or not to do with the artwork that might have been, definitely was, could have been, or never became the artwork that was or was not included in the KR client (or not).
In fact, while we all know Grimm's an artist for Ultima Online, I'm pretty sure none of us can conjur any proof of it.
