Very nice, guys! lol
I have seen many things since i started freelancing so many years ago... I roughly started in 1988/89. There have been many artists and companies that have either been inspired by, or totally ripped off another artist/company! I put out some art in the early '90s that showed up almost line for line in a comic book... the company i did the work for was pissed to say the least! I, however, was incredibly flattered.
I've been to quite a few conventions (like GenCon) where other artists have complimented my art and said that it had inspired them - and, just so i'm not tooting my own horn - i've overheard others say the same of both Tom and Wes as well.
Oddly enough, you don't hear of too many writers of games complaining that they got ripped off! (unless they're from GW!)
