Your SG Stages/Zones

If you programmed Sonic Generations, what Stages/Zones would you include?

My picks:

Sonic the Hedgehog - Green Hill Zone
Sonic the Hedgehog 2 - Metropolis Zone
Sonic the Hedgehog 3 - Ice Cap Zone
Sonic and Knuckles - Flying Battery Zone
S3&K - Hidden Palace Zone
Sonic Spinball - Toxic Caves Zone
Sonic Adventure - Egg Carrier
Sonic Adventure 2 - Radical Highway
Sonic Heroes - Final Fortress
Sonic Next-Gen - Wave Ocean
Sonic Unleashed - Spagonia (Day)
Sonic Colours - Terminal Velocity

If I had my say, Green Hill Zone wouldn't be in there. it's overused. Nuff said.

The only one's I'd like to see specifically are Crazy Gadget, Ice Cap and lava Reef.

My Stages Would Be...

Sonic 1: Green Hill/Starlight
Sonic 2: Casino Night/Metropolis
Sonic 3: Carnival Night/Ice Cap
Sonic & Knuckles: Lava Reef/Sky Sanctuary
Sonic Adventure: Twinkle Park/Speed Highway
Sonic Adventure 2: City Escape/Green Forest
Sonic Heroes: Bingo Highway/Rail Canyion
Sonic Next Gen: Radical Train/Kingdom Valley
Sonic Unleashed: Chu-Nan/Holaska
Sonic Colours: Sweet Mountain/Planet Wisp

I add Rail Canyon. ^_^
And Kingdom Valley.

Those levels would look pretty beast in both styles, shame Sega can't add more levels.
