Honestly, I'd totally dig a a sic fi and fantasy themed lands and I really like @Jevlin's ideas for names. Not quite sold on the romance land, if only because I'm not that big of a fan of those comics in general, but such a thing could work in the right hands.
As for rides, I'd totally want a ride based off of my Alpha Alpaca comic similar to Universal's Amazing Adventures of Spiderman.
Also, maybe a dark ride/roller coast hybrid or motional simulator/movie for DRGN. Only problem is I don't know if a DRGN ride would belong in the Sci-fi land, or the fantasy land.
As for other hypothetical rides, had a pretty fun idea for a Dueling Dragons-esque roller coaster of two different, yet interlocking red and blue coasters based off of @Rodimus13's Hue Are You or a dark ride of sorts based off of @ghostieblu's Mirror Monster. Heck, maybe a restaurant based off of the Black Deer from @Chita's Burning Shadows in the Fantasy land.
