The difference being that VSCs confer only partial size category bonuses/penalties. A Colossal creature wouldn't gain the AC/attack penalty, grapple modifier, hide modifier, and carrying capacity modifier that a Titanic creature would have gained. In addition, the Colossal creature is susceptible to a wider range of attacks dependent on the target's size category (crush, stomp, swallow whole, trample, etc).
The rules in the Bestiary suggested that spheres/cubes get +1 size category (not just a VSC), but since you recommended a slam damage of Slam+1, it seems that you're suggesting that spheres and cubes receive +1 VSC instead. I'm leaning toward the VSC increase rather than the complete size category increase.
Also, one more question. In v5 of the Challenging Challenge Ratings PDF, you give the following base speeds (presumably for bipeds):
Fine = 5 ft.
Diminutive = 10 ft.
Tiny = 15 ft.
Small = 20 ft.
Medium = 30 ft.
Large = 40 ft.
Huge = 50 ft.
Gargantuan = 60 ft.
Colossal = 70 ft.
But in the Bestiary, you give the following base speeds for bipeds:
Fine = 5 ft.
Diminutive = 10 ft.
Tiny = 15 ft.
Small = 20 ft.
Medium = 30 ft.
Large = 40 ft.
Huge = 60 ft.
Gargantuan = 80 ft.
Colossal = 120 ft.
Which set of values is the more accurate one?
Edit: I just got a request to do a Malboro from Final Fantasy X. Here's a pic:
http://www.ffcompendium.com/EspMon/marlboro10.jpg. And here are my calculations for its dimensions, determined by using the height comparison in FFX-2's built-in bestiary:
Total Height = 19 feet
Total Width = 37.5 feet
Total Depth = 33.5 feet
Head Height = 14 feet
Head Width = 15 feet
Head Depth = 13.5 feet
Neck Height = 1.5 feet
Neck Width = 10.5 feet
Neck Depth = 9 feet
Tentacles Height = 3.5 feet
Tentacles Width = 37.5 feet
Tentacles Depth = 33.5 feet
Maw Length = 13.5 feet
Maw Width = 5 feet
Head Volume = 1485 cubic feet (Ellipsoid)
Neck Volume = 111 cubic feet (Elliptical Cylinder)
Tentacle Volume = 329 cubic feet (Elliptical Cylinder, 987 / 3 to take space between tentacles into account)
Total Volume = 1925 cubic feet
Estimated Density = 75 pounds per cubic foot (fleshy/bony plant)
Estimated Mass = 144,375 pounds (72.1875 tons)
Does that sound right to you? It's a 72-ton creature, and by my HD-tonnage guidelines it should have about 27 HD (or 16-17 HD by the Bestiary's guidlines). However, it's only 19 feet tall, and 27 or 16-17 HD would make it a Gargantuan creature. Then again, the head is roughly spherical though. How much HD would you give it, U_K? And if it ends up having 27 or 16-17 HD, should I be also trying to give it a CR of 27 or 16-17 under v5 of the challenge rating PDF?
