Question: how many varieties of coasters can they build? Pretty soon they will have to remove some older attractions to build new coasters, won't they?
SDC is missing:
1.Traditional woodie, either out and back or twisty
2.Suspended coaster, I guess you could say B&M Wingriders are their new suspended coasters . They are now building family suspended coasters like Vekoma. Pretty much put an end to their floorless version similar to Wildfire. They are now building family suspended coasters like Vekoma.
3. Dive coaster
4. bobsled type coaster
5. Mouse style coaster, custom kind that Mack seems really good at.
6. Spinning coaster
7.Boomerang style, Gerstlauer has put in a few family type of these in Europe lately and their the oft cussed Vekomas that still sell.
8.Trick Track, drop track or trick track like Firechaser unless we want to get technical with finicky Powerkeg.
9.Mega coaster, the steel giants that are inversionless but with insane speed and hills
10. 4d coasters
11. Beyond vertical drop coasters. Gerstlauer Euro figters and S&S El Locos
12. B&M flying coasters like Manta at SeaWorld Orlando
And a few more
