I made my own webmail client in 2001. The killer feature was a Heart button that one-click opened a new mail addressed to my then-girlfriend-now-wife. I've never seen that feature replicated then or now. And since it was hard-coded to my girlfriend, it was clearly (hopefully!) not broadly applicable.
Why hate on that game? It had both great puzzles (challenging yet approachable) AND was pushing the envelope of CD-ROM as a new technology, specifically the use of video + celebrities.
