Had WoZ. Gone. Had Tron. Still do!
For me, theme is a big part. Yeah, you can love a game despite theme, but it's Tron man!
WoZ definitely has the technical advantages. Lots of gorgeous visuals and a goodies.
But Tron is, to me, much more rewarding. Lots of mods to do to it which is a biggie for me. Parts readily available from any number of sources.
