Yah, some like the Astrosmash stuff are pretty minor and I didn't actively seek them out but I have become more aware of them as I'm sorting through stuff. There's also a lot of the original book style that under the later INTV releases became simpler boxes. Usually for my CIB collection I'm after the original version. In fact, my CIB collection officially is complete today as my recent Spiker CIB purchase arrived. 12 years to do so!
As for the bagged Spiker, I actually have that one sealed and I'm pretty sure it's rarer than the CIB, but the CIB will always command a premium. As a matter of fact, I believe there are three label variations in total. That would be expensive!
I find that as I complete a notable variation collection, I move on to the next more obscure set, plus there's always hardware variations and the paperwork as well. It can be a wee bit addictive.
Hey, another picture that your owe us! the bagged and sealed Spiker!, I never seen a bagged Intv game!
