Okay, well, I haven't actually got any new information for you readers regarding the wondrous SegaWorld unfortunately. However, I did dig these up;
First, the weird SegaWorld Sonic pom /banner thing. Apparently there were several different designs, but I only have this one myself. It proudly rests, stuck to my CD rack.
This is the glorious badge I was trying to get from the broken badge machine dispensing thing. Well, I got given it by staff along with the pom above as a friendly bonus.
And this is a pin I didn't know I had. I don't actually remember getting it, but I will make sure not to lose it now. Something about it's nice and stylish, even though it's just a little SegaWorld logo. I couldn't find the SegaWorld pen I used to have, but it wasn't all that fantastic. It was just a clicky white pen with the above Sonic / SegaWorld logo. So there you go, those a few of the pointless items I've acquired in my Sega fandom.
