Nintendo definitely should come to Universal - and would give them tons of timeless characters on par with Mickey and Pooh Bear
But it would work better as a third gate of its own!! 100-150 acres is more than enough!
KidZone should stay Nick, Illumination, DreamWorks or if not in Toon Lagoon, Hanna Barbera as well
Video games have nothing to do with USF's motto "Ride the Movies" anyway...
Universal's Game Realm (with Sega, Capcom, and Microsoft contributing a little: about 75% Nintendo though)
1. Wii Plaza
2. Mushroom Kingdom with Yoshi's Island mini-land
3. DK Jungle
3. Fun Forest (Kirby, Pikmin, Sonic, etc) - area name would change though
4. Pokemon Village (the Seuss area/KidZone of the park)
5. Hyrule
6. Intergalactic Port (Metroid, Halo, Star Fox, Megaman, Portal, etc)
7. 8-Bit Street (PacMan, Frogger, Ice Climbers, etc)
USF - Based on Movies/TV
IOA - Based on Literature/Stories
UGR - Based on Video Games
It would bring their basis on forms of media theme for the resort into full circle
